John Croteau - President and CEO
Thank you, Leanne. Welcome, everyone, and thanks for joining us today. I'll begin today's call with an overview of our second-quarter results for fiscal 2016 and then turn the call over to Bob McMullan, our CFO, who will review our financial performance in further detail. I will then conclude today's prepared comments by providing a summary of our execution during the quarter, followed by guidance for the fiscal third quarter of 2016.
Straight to the results: I am pleased to report that for our fiscal second quarter of 2016, revenue was $133.6 million, exceeding the top end of our guidance, with gross margin coming in at 58.1%. Net income was $25.7 million, with earnings per diluted share beating the top end of our guidance at $0.46 per share.
Networks was up strong sequentially, with continued growth across all optical markets, spanning PON, long-haul metro, and data center applications. Our catalog business performed as expected, with A&D flat and multi-market up sequentially. All in all, strong demand across our end markets enabled us to beat the top end of our guidance on revenue and EPS. Another quarter of solid execution by the team.
Now let me turn it over to Bob to review our fiscal second-quarter financials in more detail.
Bob McMullan - SVP and CFO
Thank you, John, and good afternoon, everyone. During the course of my comments as well as those made by John, all income statement amounts and percentages will be discussed on an adjusted non-GAAP basis and are provided to enhance the understanding of our core operating performance. A reconciliation of each amount to the most comparable GAAP measure is included in today's earnings press release.
Revenue was $133.6 million during the second quarter, representing a sequential increase of 15.4% compared to revenues of $115.8 million in the prior quarter and an increase of 30.4% compared to $102.4 million in the fiscal second quarter of 2015.
Revenue by end markets: networks, $96.3 million and 72.1% of total revenue; multi-market, $19.2 million and 14.4%; and A&D, $18.1 million and 13.5%. Networks' revenue contribution was up 0.5% compared to fiscal first-quarter's contribution.
Gross profit in the fiscal second quarter was $77.6 million or 58.1% of revenue compared to $68 million or 58.7% of revenues in the prior quarter, $59 million or 57.6% in the fiscal second quarter of 2015. Gross margin was essentially flat sequentially. Short-term contribution from lower gross margin products from fabs we are in the process of consolidating into our Lowell facility are reducing gross margins from our target operating model of 60%.
In terms of operating expenses for the second fiscal quarter, total operating expenses were $45.2 million compared to $40.3 million in the prior quarter and $35.3 million in the prior year's quarter. Operating expenses were up for full-quarter expenses from our recent acquisition and higher variable compensation expense.
Research and development expense for the fiscal second quarter was $23.1 million. This compares to R&D expense of $21.5 million in the prior quarter and $18.2 million in the fiscal second quarter of 2015. R&D as a percent of revenue represented 17.3% in the fiscal second quarter compared to 18.6% in the previous quarter and 17.7% in the prior year's quarter.
Selling, general, and administrative expenses for the fiscal second quarter was $22.1 million. This compared to SG&A expense of $18.8 million in the prior quarter and $17.1 million in the prior year's quarter. SG&A as a percentage of revenue represented 16.5% in the fiscal second quarter compared to 16.2% in the previous quarter and 16.7% in the prior year's quarter.
Income from operation was $32.4 million or 24.3% of revenue. This compares to $27.7 million or 23.9% of revenue in the prior quarter, $23.7 million or 23.2% of revenues in the prior year's quarter. Operating margin increased 40 basis points, realizing greater operating leverage.
Interest expense of $4.1 million in the second quarter was flat compared to the prior fiscal quarter and down from $4.3 million in the prior year's quarter. The year-over-year decrease was due to lower outstanding debt. Other income of $1.9 million represents revenue from a consulting contract from our automotive divestment that continues through fiscal 2017.
Turning to income taxes, our effective income tax rate for the fiscal second quarter was 15%, which is also our normalized rate for fiscal 2016. This tax rate was consistent with the prior fiscal quarter and down from 18% in the fiscal second quarter of 2015. We paid cash taxes of $100,000 in the second fiscal quarter.
Our fiscal second-quarter net income was $25.7 million or $0.46 per diluted share compared to fiscal first-quarter net income of $21.8 million or $0.40 per diluted share and net income of $16.5 million or $0.31 per diluted share in the prior year's quarter.
EPS grew sequentially 15% and 48.4% over the same quarter in the prior year as we continued to leverage operating expense, leading to net income expansion. The share count used to compute fully diluted EPS was 55.4 million shares for the second fiscal quarter, 55 million shares in the fiscal first quarter of 2016, and 52.5 million shares in the fiscal second quarter of 2015.
EBITDA, or earnings before interest, taxes, depreciation, and amortization, was $39 million, up from $33.5 million in prior fiscal quarter and up from $27.4 million in the prior year's quarter. GAAP cash flow from operations was $19.5 million in the fiscal second quarter as compared to $15.5 million in the fiscal first quarter, or 75.9% and 71.1%, respectively, of non-GAAP net income.
After deducting capital expenditures in each fiscal quarter, free cash flow was $8.4 million and $8.8 million, respectively, or 32.7% and 40.4%, respectively, of non-GAAP net income.
Turning to the balance sheet: at fiscal quarter's end, our cash, cash equivalents, and short-term investments were approximately $81.8 million, up $4.2 million over the prior fiscal quarter. Accounts receivable at $91.6 million compared to $84 million at the end of the prior quarter. Days sales outstanding were 62 days compared to 63 days.
Inventory was $107 million compared to $101 million in the prior quarter. Inventory turns were 2.1 times compared to 1.9 times in the prior fiscal quarter. We are building inventory in line with our future revenue expectations and specifically to allow for buffer stock for customers affected by the closing and consolidation of fabs into our Lowell facility.
Long-term debt was $341.4 million, inclusive of acquired capital leases, and we had $130 million availability in an undrawn credit line. Capital expenditures in the fiscal second quarter were $11.1 million for 8% of revenues compared to $6.7 million or 5.4% of revenue in the fiscal first quarter.
Capital expenditures are necessary as we continue to grow our engineering resources and design centers globally for emerging initiatives such as base stations, silicon photonics, 5G, high-speed lasers; also, expanding our process technologies such as GaN on silicon, silicon germanium, and indium phosphide; and for multiple customer support locations as well as our manufacturing, test, and packaging capabilities to expand capacity, reduce process times, and meet customer expectations.
Related depreciation expense for the fiscal second quarter was approximately $4.8 million as compared to $3.9 million in the prior quarter and $3.7 million in the prior year's quarter. Our investments in capital expenditures exceed our current level of depreciation expense. This reduces the percentage of free cash flow as compared to non-GAAP net income. Specifically, fiscal year to date we generated positive free cash flow of $17.2 million after capital expenditures of $17.8 million.
Back to you, John.
John Croteau - President and CEO
Thanks, Bob. I'd like to start by providing some color on optical. We had another quarter of strong sequential growth in optical, fueled by modulator drivers for long haul/metro and lasers for access in backhaul applications. Last quarter, long haul and metro growth was driven by several major customers servicing the Verizon, AT&T and China Metro build outs.
Demand for our CFP2-ACO drivers continues to grow, with very strong backlog that will drive growth through the second half of 2016. Our laser capacity continues to ramp in Lowell, and we saw double-digit sequential growth in PON and exceptionally strong growth in backhaul. Our share continues to expand unabated.
In data center we saw initial revenue and strong backlog for our high-performance analog products to support demand at Facebook and Amazon. We also began volume production ramp of 25-gig lasers in support of 100G in data centers.
The strong results we achieved this quarter were further underscored at OFC last month. Coming out of the show, it's clear from the level of interest and deep customer engagement that MACOM has established a truly preeminent position in the optical space across a diverse set of products, technologies, applications, and market segments.
Now let me share some of the learnings from OFC. Word at the show was very bullish on long haul/metro as deployments expand at 100G this year and quickly move on to 200G and 400G. MACOM was the only Company at OFC who was shipping in production six different flavors of modulator drivers that cover the various classes of CFP2-ACO.
We announced the industry's first 64-gigabaud linear modulator driver that supports data rates up to 400G and beyond. This product is one of the key building blocks to enable the next generation of single-wavelength 400G systems.
A positive surprise and another key learning was that the growth we've seen in backhaul to date is only in the early stages of market ramp. Forward-looking growth prospects now exceed our previous expectations, and we expect to see continued growth and backhaul moving into the second half of 2016.
Likewise in PON, where we thought the market might saturate by 2017, we heard at the show that there is a push to drive higher bandwidth for enterprises as well as residences, driven by the advent of 4K set-top boxes. This leads to an entirely new buildout of 10-gig access for fiber-to-the-home. Where we thought that part of our business would possibly flatten and decline in the longer-term, we now believe it, too, will grow for the foreseeable future.
In data centers the big takeaway from the show was the resounding validation of our L-PIC and SAEFT strategy from all major cloud service providers. They acknowledged and clearly understood our intention and ability to drive the economics of 100G optical connectivity within data centers. We are confident that this opportunity will be everything we had hoped for as articulated during our analyst day.
Overall, coming out of the show, customer response across all optical markets and subsegments reaffirmed our belief that we have established a preeminent position as the pure-play supplier of high-speed analog and photonic components in the optical world.
Touching briefly on active antennas, A&D performed as expected. We see continued progress in the MMIC programs and tile-based opportunities, with nothing new to report on the customer order front since our analyst day last month.
Moving to GaN, we continue to execute on our GaN vision and are 100% on track with process qualification as articulated at analyst day. Our confidence grows daily.
On the customer engagement front, we're rapidly converging on program wins, executing to clear schedules and customer requirements for certain 4G LTE regional deployments. These programs address mainstream LTE deployments where our GaN value proposition shines, delivering a degree of efficiency, integration, size and performance that could never be realized by a incumbent LDMOS technology, making our solution a clear and winning choice.
Underscoring our belief that we are at the tipping point, as you saw in our announcement earlier today, we've initiated legal action against Infineon in federal court in Los Angeles to defend our rights to use certain GaN technology in MACOM's core RF markets. This technology was originally developed and patented by Nitronex, which MACOM acquired in 2014.
Since its acquisition of International Rectifier in 2015, Infineon has failed to honor the letter and spirit of certain IP agreements between Nitronex and International Rectifier relating to the Nitronex GaN technology. These agreements functioned effectively for many years between IR and Nitronex and later between IR and MACOM. However, almost immediately after it closed on its acquisition of IR, Infineon began to try to unilaterally renegotiate the agreements to usurp our rights.
When we declined to agree to Infineon's unreasonable demands, they responded by concocting claims to interfere with our rights. We believe that Infineon's conduct is a breach of the Nitronex IR agreements, and we've asked the court to confirm our position.
Infineon's actions are an opportunistic attempt to gain access to our burgeoning market for GaN RF products by improper means. It's regrettable that Infineon has attempted to engage in such strong-arm tactics, but we intend to vigorously protect our rights, and we expect to be fully vindicated in court.
We've built a highly successful business that has benefited both the electronics industry and our shareholders through the acquisition and integration of companies and intellectual property that is supportive of our strategic plans. Defending those intellectual property rights is core to that success.
To some extent it's to be expected that we'll have to defend our rights as we begin to dislocate markets and drive major share transitions from old-school incumbents. Bullies don't take losing lightly. Infineon's behavior is a clear indication that even they believe our GaN technology is at the tipping point of market adoption. Adoption of MACOM GaN for RF threatens large silicon incumbents like Infineon, who have an incentive to retard rather than accelerate innovation.
The potential stifling of innovation and other anti-competitive effects of Infineon's bullying tactics are deeply troubling. Allowing such behavior by industry behemoths to go unchallenged would lead into erosion of ethical business practice and the rule of law and would have a chilling effect on the innovation-driven US economy.
To our MACOM shareholders, know that we are committed to vigorously defending our IP rights against infringement or disruption by any party, regardless of that party's size, stature, or circumstances. It's an important part of our stewardship of your investment in our Company. Indeed, we have previously prevailed against large company infringement of our rights, such as in 2014 when we protected our Ford business by securing a permanent injunction against Laird for infringing our IP.
Let me close by emphasizing something. The outcome of this litigation is immaterial to our near-term operating results. It has everything to do with securing long-term returns for those who have honestly and genuinely invested in moving the industry and society forward.
With that, let me bring it back and talk about next-quarter guidance. For the fiscal third quarter ending July 1, 2016, MACOM expects revenue to be in the range of $138 million to $142 million. Adjusted gross margin is expected to be between 57% and 59% and adjusted earnings per share between $0.49 and $0.52 on an anticipated 56.5 million diluted shares outstanding.
I'd like to close today's scripted remarks by thanking the team for another quarter of solid execution. Operator, you can now open the call to questions.
Operator
Thank you, sir. (Operator Instructions) Blayne Curtis, Barclays.
Blayne Curtis - Analyst
Thanks for taking my question, and nice execution. John, you probably -- I don't know how much you can talk about -- on the litigation. But one, how much is it costing you in the June quarter? Has that kind of layered in yet, or is it just starting?
And then I guess what I'm confused on is there was an agreement where Infineon had rights to the power product. Is anything that Infineon is doing going to impact your ability to sell the GaN on silicon into some of the markets you were targeting first, like base stations?
John Croteau - President and CEO
Yes, good question, Blayne. That's exactly the point. The bottom line is we have a very, very, very clear legal case. It became pretty apparent shortly after the acquisition of IR by Infineon that they were not going to be planning to adhere to the letter or spirit of any of the agreements that any of the agreements that worked quite well for 10 years preceding that between IR and Nitronex.
I mean, to put it bluntly, they just aspired to get access to be able to participate in base stations along with us. So if -- I don't anticipate it having, first of all, any material effect on the short to medium term. The real question is: long term, do they get to try to steal away some share from our investments?
Blayne Curtis - Analyst
Got it, thanks. And then the network business had a large step-up in March. Just curious, as you look into June, with the guidances by segment, I was just curious what areas you do expect to be the strongest? And then within network, where are you seeing that strength?
John Croteau - President and CEO
Yes, good question. So you're right; networks is where there is incredible strength across every single one of our optical subsegments. The PON -- we anticipate growth and access there. Backhaul is absolutely exploding. We saw double-digit growth in both of those -- very, very strong growth and anticipated growth. Backlog is tremendous for both the metro buildouts as well as data center with our high-performance analog products. So everything is teed up for some remarkable growth in the network side through the second half of the year.
In terms of the rest of the segments, we are cautiously optimistic that we're going to see some good recovery in the catalog business, but that's -- you know, at this juncture is still hard to predict. But it's pretty much up and to the right for us -- everything at this point.
Blayne Curtis - Analyst
Great. Thanks, John.
John Croteau - President and CEO
You're welcome.
Operator
Mark Delaney, Goldman Sachs.
Mark Delaney - Analyst
First question is on the base station opportunity. John, in your prepared remarks and also in the press release, you mentioned making good progress towards getting those design wins for LTE. Can you just give us an update on what milestones you still need to achieve in order to convert those into revenue?
John Croteau - President and CEO
Yes, the big one that still lays out there is process qualification in our first production in fab. And that is 100% on track, as outlined at our analyst day. The further you get into this, the greater the confidence grows. I would say it's very, very high confidence at this point. If something were to go wrong, it would be at this point a surprise, honestly.
Beyond that, obviously the next critical thing is customer engagement. And the beauty of it is we've gotten clear targets lit up, with initial commercial discussions closed on some initial production ramps of what I would describe to be mainstream 4G LTE deployments. So we're not talking about the esoteric high-end, high-frequency stuff where GaN has traditionally played. This is going after right in the heart of LDMOS land, which is great news.
And the design targets that we are given is right in a sweet spot in terms of performance, integration, and efficiency that can't -- technically could not be met by the incumbents. And that's the reason why they were awarded to us.
But, you know, there's still execution on the product and the design validation. And that's going to be happening through the month of May, as I understand it. So it's a -- and similar things are lining up in the other major customers. And, by the way, I should say that's one of the three majors, and the other guys are opening up in a very similar manner. So it's all looking very, very favorable, as articulated in our analyst day.
Mark Delaney - Analyst
That's helpful. And for a follow-up question on Aeroflex, can you just give us an update on how the integration is going in terms of moving those products into the Lowell fab? And then on the cash flow side, just a sense for how much inventory you need to put on the balance sheet related to Aeroflex as you move through that transition.
John Croteau - President and CEO
Yes. I'll defer the second part of the question to Bob.
But in terms of the integration, absolutely spectacular. We've become quite good at this. In terms of integrating factories. I can tell you, the soft issues of being able to engage the people and to be able to bring factories in both Sunnyvale and Londonderry, New Hampshire, to closure through the course of this calendar year -- it's a core competence, in my opinion. And it's going right on track, if not ahead of schedule.
And I'll echo Robert's comment at the analyst day that we should be able to realize that gross margin expansion associated with those closures sooner rather than later. But the plan is calendar 2016.
Mark Delaney - Analyst
Bob, the second half?
Bob McMullan - SVP and CFO
Yes, Mark. It's less than 10% of total inventory. So it ranges by what process they state it's in -- whether it's raw materials, and you add in some work in process and finished goods. But the point is there is to provide the confidence to the customer that they can get what they need.
Mark Delaney - Analyst
Thank you very much.
Operator
Vivek Arya, Bank of America Merrill Lynch.
Vivek Arya - Analyst
Maybe one more on this Infineon litigation. Just to clarify, does this need to be resolved one way or another before you can ship into the base station market and recognize revenue? Or the resolution just impacts Infineon's ability to be a player in this market?
John Croteau - President and CEO
It's the latter. You know, it's the license rights. I'm kind of hamstrung here, because the original Nitronex IR agreement has confidentiality provisions, so I can't really speak details of what's been claimed and counterclaimed, and so on.
But, you know, the bottom line is our rights and our abilities are black and white. That's not the issue. What it really comes down to is: will Infineon be able to annex our position or part of our position in, particularly, base stations, if not beyond? And our position is clear. We are not negotiating with ourselves. They have no rights, and we've asked the court to confirm our position.
Vivek Arya - Analyst
Got it. And then as a follow-up, I think, John, you mentioned upside to some of the backhaul revenues, and then also some improvement in the cable business. Is there a way to quantify some of this upside that -- do you think you will see that more in September or December? Any way to help us better understand this upside? Thank you.
John Croteau - President and CEO
Yes, you know, we are really reluctant to provide breakdowns by segment quantitatively rather than providing color on moving parts. I can tell you, on the backhaul side we grew over 50% sequential on the backhaul business. And we thought, well, you know, it just might be market exuberance. This wireless infrastructure segment tends to be very -- it's been quite a roller coaster.
But the interesting experience we had at OFC is that that's not the case; that the market is really just in the early stages of deployment of bringing out fiber backhaul, and that the customers are actually anticipating sustained growth in that segment. Now, whether you can put together back-to-back quarters of that kind of sequential growth is not what we're suggesting. But it's something that we thought was actually a mature market penetration, and it's not whatsoever.
Likewise, a similar situation with PON. We put together double-digit sequential growth in PON, and the outlook looks similar. The product that we are shipping out of Lowell is deemed to be higher quality, has associated benefits of lower cost of -- in product manufacture. And even in an environment where you might see some softening in the overall PON market, customers are awarding us more and more and more share. So it's just a great story right now.
Vivek Arya - Analyst
Got it. And maybe quick one for Bob. I think, Bob, in the past there was a sense that at some point you could get back to the 60% gross margin, 30% op margin level over the next several quarters. I was wondering if you could walk us through what the drivers would be from here on to get to those targets? Thank you.
Bob McMullan - SVP and CFO
Yes, as we said, the current state of the acquisitions -- the recent acquisitions, probably best in Metelics, is bringing down our overall preacquisition MACOM gross margin from the 60%s into the 50%s, the high 50%s, as we continue to translate those businesses to the MACOM plan -- and that will happen over the next couple of quarters -- we'll get closer to that 60% and possibly exceed it.
Operator
Harlan Sur, JPMorgan.
Harlan Sur - Analyst
Nice job on the quarterly execution. A&D in multi-markets -- you know, on the last earnings call, you guys had described the demand environment as cloudy with sort of flattish backlog coming into the March quarter. But at the same time, you guys did think you were at a bottom.
You guys ended up delivering pretty good growth in multi-markets in the March quarter. So I guess the first question is: what drove the upside there and your cautious optimism on growth for multi-markets in June?
And then on the A&D front, it came in flattish as expected in March. Wondering if the SABR or the F-16 program upgrades start to drive some growth in the second half of this calendar year?
John Croteau - President and CEO
Yes, so the answer to the latter part of the question is yes. Second half of the calendar year is exactly when the MMIC programs turn back into sustained production.
Yes, I'd say the -- you know, it's difficult with our catalog business, other than looking at backlog trends, to really predict the broad market, the health of the broad market. And I would not describe backlog trends to be indicative of a strong upsurge. But it certainly feels like we could be seeing an uptick, but it's just too early to call.
In our guidance we are assuming relatively flat for the catalog business. So if it turns up, it would be upside to our guidance.
Harlan Sur - Analyst
Got it. Thanks for that. And then, Bob, how should we think about operating expenses beyond the June quarter? I assume that in order to hit your 30% op margin goal, I think hopefully exiting this calendar year, with the assumption that there's going to be continued revenue growth for the Company, that your OpEx is going to be relatively flattish in the June levels. Is that a fair assumption?
Bob McMullan - SVP and CFO
Yes, it is.
Harlan Sur - Analyst
Okay, great. Thank you.
Operator
Harsh Kumar, Stephens.
Richard Sewell - Analyst
Yes, thanks, guys. This is Richard in for Harsh. I just wanted to touch on the backhaul market a little bit more. I know that you talked about that being a positive surprise. Could you give a little bit more color there? And are you seeing this in a specific geography or a specific product, or where are you seeing the strength?
John Croteau - President and CEO
Sure. So the product area is in lasers. In fiber backhaul -- we inherited that business with the acquisition of BinOptics a year and a half ago. And as I said, the sequential growth was over 50% last quarter, up from, I would say, a modest -- previous modest recovery on that segment.
If you remember, go back a couple/three quarters, it had bottomed out with the China management restructuring. So its recovery was anticipated, but certainly not as strong as we saw. And, again, the backlog is -- and these are 10-G lasers. Very nice gross margin structure.
The backlog is indicative of continued growth. And again, the color we got at OFC was our customers -- and to answer your question about regional, there was no particular regional correlation. So it's global demand that that's being serviced.
Richard Sewell - Analyst
Got you. That's extremely helpful. And then specifically on the data center side, it seems like on the optical side within data centers, revenues are starting to ramp there. How should we think about that ramp in the second half of the year? And where are we from a cost structure on the data center side?
John Croteau - President and CEO
Yes. So all of the business this year is really re-implemented telecom design products. So it is not the cost-driven, cost-optimized stuff that we talked about at the analyst day.
The word at OFC was a lot of concern across a lot of customers about capacity limitations in the industry limiting the ability to supply the demand, which is ahead of their expectations. We don't think we're going to have a capacity problem servicing their demand. They are concerned about other aspects of their supply chain.
So it's all very strong. But the real inflection point is next year, when we talk about the cost-optimized solutions that really drive 100G connectivity -- the cost of it. And the fabulous news there was the message that we delivered as it related to the L-PICs, laser PICS, with the SAEFT technology was unbelievably -- not only acknowledged, but there was a kind of a feeding frenzy in front of the cloud service guys wanting to work with us directly in helping to drive the economics of their solutions. That was, frankly, the biggest news and validation for us coming out of OFC.
Richard Sewell - Analyst
Got you. And if I can sneak one more in -- that was very helpful. On the SPAR or the SPAR Tiles, when should we expect that to ramp? Is there any kind of update on that project?
John Croteau - President and CEO
Well, there's revenue contributions for the second half of this year from the production -- first production buildout for the MPAR program, full production -- the first full-production system. But if you are -- I infer from your statement you're talking about the real inflection point of full-scale production systems. That would be in 2017 at the earliest.
As we said at the analyst day, we're building our capacity plant and able -- to be able to support initial program volume production in the middle of 2017. We have nothing to report in terms of actual programs being awarded for 2017, but we are building capacity in anticipation of that timeline.
Richard Sewell - Analyst
Great. Thank you very much, and congratulations.
John Croteau - President and CEO
Thank you.
Operator
Eric Rasmussen, Stifel.
Erik Rasmussen - Analyst
Nice results. I wanted to talk about -- I have some questions on the optical business. Can you just fill us in on how you're ramping with the AAOI? I know you talked about that contribution -- it being a several-million-dollar opportunity. But has there been any sort of follow-on or changes in orders? And what does that kind of ramp look like?
John Croteau - President and CEO
Yes, I've got to be careful here. We are always very reluctant to be talking about specific business levels with specific customers. I realize we put out a press release, so we're probably asking for it.
But we began shipping against that order, and the demand continues. I would say AOI is one of multiple customers servicing data centers. So it's certainly not by any means the only one. But everything -- I don't think there's any material change in that business outlook and scheduling from the time we talked about it at analyst day.
Erik Rasmussen - Analyst
Okay, thanks. And maybe for my follow-up, for Bob: Bob, it looks like you had nice operating cash flow and free cash flow. And looks like the last two quarters now, you're kind of at a little bit more of a sustainable rate. I mean, is this what we should be expecting from this type of model? And what's -- do you have any sort of targets for free cash flow?
And then the CapEx -- I know you mentioned there's a lot of moving parts. And I think last quarter it was 8% to support a lot of new initiatives that you have. But is there a target range for that? That's all I have.
Bob McMullan - SVP and CFO
Concurrent with our target operating model that includes gross margin at 60%, the operating margin of 30% going to 40% as things -- big revenue opportunities are realized here in the future, we target a 60% free cash flow to non-GAAP net income. And that's with the assumption at the 60% level that it's a 30% operating margin, and that we're a continuing growing company making continued investment in our capacity, which is very different than a very mature company that has a lot of depreciation and not a lot of new investment in facilities.
Erik Rasmussen - Analyst
Okay, thank you.
Bob McMullan - SVP and CFO
You're welcome.

Mark Lipacis, Jefferies.
Mark Lipacis - Analyst
First question: on the BinOptics products, I think I heard you talk about a 25-gig product that you were shipping. When do you think that ships into qualified production 100-gig modules?
John Croteau - President and CEO
Last quarter.
Mark Lipacis - Analyst
Pardon?
John Croteau - President and CEO
Last quarter.
Mark Lipacis - Analyst
Oh, sorry. You're shipping already into production modules. Okay, great.
And then on Infineon, how much is this hitting OpEx? Like, how should we think about the expense associated with this? And is Infineon shipping GaN on silicon right now, or are you just seeing them in bake-offs, and you're just trying to head them off at the pass? That's all I had. Thank you.
Bob McMullan - SVP and CFO
Yes, we are treating the legal expenses as we did with the Laird, because our confidence in the legal case -- some of these expenses may be potentially reimbursed to us as part of the damages we claim. So they are not in our operating earnings today. If that situation changes, we may reevaluate that. I have no comment with respect to what Infineon is doing in there.
John Croteau - President and CEO
Yes, so, okay. They ship GaN on silicon products and inherited the business from International Rectifier, which focused on power management applications, so switching power supplies, for instance. I guess I can't speak to their ambitions or products in the RF space. I'll leave it at that.
Mark Lipacis - Analyst
Fair enough, thank you.

Steve Smigie, Raymond James.
Steve Smigie - Analyst
I just want to follow up with some of your recent products on the optical/optoelectronics side. You have some solutions where you're integrating the CDR in with the laser driver, and I was just curious if you could talk a little bit about how important you think it is to have integrated parts like those versus keeping the parts separate and giving, maybe, more flexibility to customers versus a more fully integrated design. And I guess beyond that, would you argue that you've pretty much got both sides of that covered in any event, so kind of whatever the customer wants is what you can deliver?
John Croteau - President and CEO
Yes, your last point is spot-on. It was going to be what I was going to say -- that, you know, different horses for different courses. Some customers would prefer things less integrated, some more integrated.
I would describe it this way. Integration is also a double-edged sword. The weakest link in that combination defines your success. We happen to have a spectacular, unequivocally highest-performance, lowest-power-consumption CDR capability. So integrating that for the most cost-sensitive applications made all the sense in the world.
It is incredibly successful. When you talk about things like 100-gig in data center connectivity, it's a requirement. There is zero ambiguity about that integration and that particular configuration being important. But I would not pretend to say that that is singly the case across all customers in all subsegments.
Steve Smigie - Analyst
Okay. And is silicon germanium the way to go in terms of material? Or again, it's more what the customer wants, and you can provide a variety of materials there?
John Croteau - President and CEO
Yes. So for that class of the high-performance analog stuff, long-haul/metro type power levels that you need to drive require indium phosphide, previously gallium arsenide. When you talk about a relatively short reach, whether it's PON or the CDRs and TIAs for data center connectivity, for instance -- absolutely, SiGe is the way to go.
So it's -- we've got all of the above, whether it's data center, PON, backhaul. We've got every flavor for every potential subsegment.
Steve Smigie - Analyst
Okay, great. If I could sneak one more in: in terms of data center, do you anticipate that you would see greater strength at something like a 2-kilometer range? Or do you think sort of something like 300-millimeter could be where you're expecting to see a lot of your growth, say, over the coming year?
John Croteau - President and CEO
I think it's too early to predict the relative growth between the two. I would say different customers -- different customers will engage different design objectives. And again, I wouldn't pretend to be able to have our crystal ball predicting which is going to be the biggest.
DCI is the thing that's happening right now between data centers. But when you talk about connectivity within the data center, the answer is probably entirely different depending on which hyperscale data center, which system guy, and which cloud service guy.
Steve Smigie - Analyst
Great. Thanks a lot.
Operator
CJ Muse, Evercore.
CJ Muse - Analyst
I guess first question: Bob, you've been pretty clear in terms of the headwinds near-term for gross margins from the two acquisitions. But just curious, as we think about networking ramping in the back half of the year and the various products that will be coming in, as well as GaN on silicon, how should we think about the trajectory for gross margins?
Bob McMullan - SVP and CFO
CJ, I think we'll see the progression of gross margins continue to increase. Again, we feel pretty confident about getting back to that 60%, and that's an overall product mix statement -- that that mix, as we continue here, will get us to the 60% as we exit the year. I hesitate -- I just said a prediction and guidance beyond the quarter ahead of us, which we don't normally do. (laughter) But well done for you. You got me to do it.
CJ Muse - Analyst
Well, I guess the question is also partially: are there any headwinds/tailwinds that we should be thinking about as new products ramp?
Bob McMullan - SVP and CFO
Not in this stage of the environment, in our opinion.
John Croteau - President and CEO
Yes. I'd suggest -- here is the way to think about it. With continued growth, that growth continues to come in high margin business. So that 60% number that we talked about preacquisition last quarter continues to expand. And then you get some significant -- very significant dilution on top from the first full quarter of operations from the acquisitions.
As we address that dilution from the gross margin, you're going to see that gap drop. And again, with the continued growth this quarter and next quarter and the continued growth -- you know, start doing the math. You can see why Bob slipped and provided some additional guidance.
CJ Muse - Analyst
Great, thanks. And I guess as my follow-up, going back to earlier questions around GaN on silicon: you talked about needing that process qual'd. But curious -- once that comes in, what would the timing look like for first revenues there?
John Croteau - President and CEO
So, you know, the difficult thing to predict is when we deliver on these main deliverables, exactly when the deployments happen and when the customers -- you know, there are scenarios where they come in very rapidly, and there's scenarios where they delay a quarter or so.
So I'd put it this way. Our position hasn't changed. There are scenarios where this calendar year we have initial production ramps. There are also scenarios where those same programs delay into the first and second quarter next year. At the very early stage of all these ramps, it's the absolute most difficult thing to predict, other than the fact -- the more we get with the law of large numbers, the likelihood of getting something coming in as a bluebird increases. But when you only have the first one or two, it's so hard to predict. So we really want to manage expectations.
To me the most critical thing is: as we get over the goal line with the qualification, and we start landing programs, and we start expanding our footprint, and we get fully qualified with the three major guys, it's very strong up and to the right. And then it becomes the same kind of operational challenge for GaN ramping as we had with lasers last year, for instance, which is exactly the kind of challenge you want to have.
CJ Muse - Analyst
Thanks so much.
John Croteau - President and CEO
You're welcome.
Operator
Quinn Bolton, Needham.
Quinn Bolton - Analyst
I'll offer my congratulations on the nice results and good guidance. John, I just wanted to come back; it sounds like really across-the-board strength in the optical business. I'm just kind of wondering -- it feels like from your comments your backlog visibility, if anything, over the course of the March quarter and to date in April is probably extended relative to where it was 90 days ago. I was hoping you might be able to comment on that.
And then for that optical business, I know you were a little bit capacity constrained late last year. And now that you're ramping Lowell, is there any part of the optical business where you're capacity constrained that might be causing an extension? You know, sort of in lead times or visibility? Or is all of that extension of your backlog really purely demand-based? And then I've got a couple of follow-ups.
John Croteau - President and CEO
Okay. So lots of questions wrapped in nested DO loop there. (laughter) So visibility has absolutely improved, as I mentioned, at OFC. And the concern was capacity availability to be able to service the growth in both metro and initial data center this year. So that absolutely leads to greater visibility.
The visibility on the laser side is spectacular. The agreements we have with the major customers are extended through the second half of the year. We'll soon be engaging per-share awards for next year, and all that looks extremely favorable.
I would say the only -- I won't say capacity-related -- issue is we are in the early stages of ramping 25G lasers for 100-gig assets access in data centers. And that really is -- you know, it's not capacity as much as yield. You want to be able to yield enough products. And it's a classic learning curve. And we're rapidly driving down that learning curve and talking to some of our supply partners, actually today -- in a call earlier today with Robert Dennehy, our operations guy -- we are confident that that's going to be a relatively unconstrained within the next quarter or so.
And if data centers to anything near what they are predicted to do, that's going to be just a rocket ship of growth, layered on top of backhaul on the laser side, on top of the metro buildouts, and so on. So it's really incredibly favorable at this point across the board.
Quinn Bolton - Analyst
Great. And I just have a follow-up on that data center. I think in the prepared comments, you mentioned some 100-gig datacom modules with both Facebook and Amazon. I just wanted to confirm that I heard that right. And if I did hear that right, can you give us -- is that mostly on the analog component side? Or are you also seeing some photonic interest with some of those big data center customers?
John Croteau - President and CEO
So the current revenue was all on the analog -- high-performance analog side. And every single one of those customers and the others that matter are absolutely engaged in the photonic side.
Quinn Bolton - Analyst
Great. And then, lastly, it sounds like your comments on your initial contract discussions for the GaN-on-silicon product may not be for the higher-frequency, say, band 41 in China; that may be more worldwide bands. It sounds like you may be engaged in some of these sort of lower-frequency -- you know, 1.8 to 2.0 gig with some of these initial contracts. Is that the right way to be thinking about the current GaN contract discussions?
John Croteau - President and CEO
Absolutely. I want to be clear, though: it's not instead of or only the lower frequency bands. You know traditionally GaN -- the engagement on GaN-related discussions is at the higher-frequency bands, which is great. Nice, wonderful business. And that's places that we expect we'll clean up.
To me, the real interesting tidbit is when you hit the more global bands and the relatively lower frequency bands. And the value proposition has to do with efficiency and integration, so on. That allows you -- you're not just operating in that top 20% of the market where GaN has had consideration. You are addressing the 80%. And that is exactly the latent opportunity with our GaN on silicon -- to take out the mainstream part of the LDMOS world.
Quinn Bolton - Analyst
That's great. Thank you.
John Croteau - President and CEO
You're welcome.
Operator
Richard Shannon, Craig-Hallum.
Richard Shannon - Analyst
Maybe just a couple of quick follow-ups here from some previous questions here. So on the 25-gig lasers here, care to venture how many customers you might have, say, six months, a year from now? And any reason why you can't have all or most of the kind of leading Web 2.0s as customers?
John Croteau - President and CEO
Yes. So it's interesting to speculate time-dimensionally how many customers. I would say the world of people who manufacture in volume is relatively finite -- would be less than a dozen guys who matter. So in terms of transaction sales, that would be the first part of the question.
And given what -- the cost benefits and the performance benefits of our etched facet lasers, my personal opinion is we will be able to sell every laser that we can produce for the foreseeable future. (laughter) And with the enabling, with the expansion for the SAEFT stuff with self-aligning etch facet lasers, even more so. And the beauty here is we're bringing that up in Lowell first. In 4-inch cost structure, we get the yields to the point where we think we'll have in the next quarter or so. And we're going to have a very strong position, not unlike that which we have in PON today.
Richard Shannon - Analyst
Just a follow-up to that, John. As I recall from the analyst event, when you introduced the L-PIC product, that was something you were going to be qualifying and might be ready for production volume early next -- or sometime next year. Is that time frame too far out? Is that something where you can see revenues this year?
John Croteau - President and CEO
You know, a year is very short at this point. And we're talking about almost in May. And just to get products in qualification -- and you're talking about cycle times through fabs that are better part of three months. At this point it's very difficult to capture revenue in this calendar year, never mind a fiscal year.
I would say that challenge, as I understand it right now, is not product performance and product qualification. It's getting it into the right volume fab, qualified -- I'd say analogous to our GaN-on-silicon issue. And the other beautiful part of it is leading up to OFC and at the time of our analyst day, it wasn't entirely clear that the value proposition was going to be understood. But I can tell you, it was a feeding frenzy. The guys who matter -- they got it.
And combined with the competence of being able to do the complete optical subassembly and the confidence and the capability, the whole investment premise of the FiBest acquisition and providing it with systonec controls, PIC and the BinOptics lasers -- man, it -- they got it.
And now it's same thing as the GaN, stuff. It's all about execution. It's all about operational execution, which is -- like I said, that's the challenge you want to have.
Richard Shannon - Analyst
Okay. Appreciate that color. I look forward to following up on that another time. Maybe another couple quick questions for me, and I'll jump out of line here.
On the backhaul, do you get the sense as to your growth that you had in the past quarter here and going forward -- is this market growth here -- is any share gains involved here? Do you have a sense of what's going on there?
John Croteau - President and CEO
Yes, there's no question. I think that the market drop last year, with the China management restructuring in China -- when we came out on the back end of that, somehow, and I think it was through superior salesmanship or something, we came out. And we think we've got a similar share now to what we have in PON.
I'm not exactly sure how we pulled that one off, other than maybe it's just we've now got the reputation of having the high quality product at the best and superior cost structure without supply chain restrictions. But -- so there was absolutely share gain involved and then a healthy market recovery on top.
Richard Shannon - Analyst
Okay, fair enough. And then just one last quick question for me on the PON side here. You've talked about some fairly substantial share gains. Is there a limit to where you can go out a few quarters? I mean, it's rare to see shares much above 50%, 60%, 70%, but it's clear that you're very willing to supply the market. But what's your limit there?
John Croteau - President and CEO
The sky's the limit. (laughter) I don't know. To be honest, my theory in the past is getting above 60% is very difficult, because customers just want to maintain a healthy supply chain. In this particular instance, the two incumbents didn't support what the customers needed and wanted, and we did, both from a capacity standpoint and cost standpoint.
I mean, the cost leverage, the benefits of the etch facet technology is such that we are the obvious guy to go to. And now the product coming out of our Lowell fab has surprisingly very high performance that leads to benefits of system cost reduction. So it's kind of an open playing field right now. At some point, I agree with you; it will balance, and the lower end part of the market may stick with some of the other -- the old incumbents. But quarter by quarter by quarter, we continue surprising ourselves, to be honest.
Richard Shannon - Analyst
Okay, great. I appreciate the detail. That's all for me, guys. Thank you very much.
Operator
Tore Svanberg, Stifel.
Tore Svanberg - Analyst
Thank you. Very nice quarter. First question for John: so obviously you got the growth engines in optical antennas and also the GaN business. Should we think of all sort of new capital investments now being targeted at share gains and comping growth in those areas? Or are you starting to see maybe a fourth leg to the stool, where you are leveraging your position already in those three segments?
John Croteau - President and CEO
So are you talking about capital investment?
Tore Svanberg - Analyst
No, I'm talking about anything that you want to do now going forward -- M&A or R&D spend. Because, you know, you have three legs, right, of growth. But there's obviously other things you can do, too.
John Croteau - President and CEO
Well, you know, I think the answer to that is quite time dimensional. We've got a lot on our plate in terms of operational execution at the current time. So we are not -- you know, we always have a healthy pipeline of potential acquisitions. These are taking time to digest. We've got factories to consolidate in this case, and the operational challenge is not small.
But I would say this year it's all about execution. It's all about execution. We don't need more secular growth drivers. We've got three healthy ones time dimensionally, diversification within those, across those. I think we've got enough strategically bitten off.
But at the same time, to be honest, before the BinOptics acquisition, before the Mindspeed acquisition, before some of these things, we didn't fully appreciate the opportunities that fell in our laps along with those. So it may be that something comes along, but I can tell you right now, we don't have visibility into those -- into another one of those of that magnitude.
Tore Svanberg - Analyst
That's very fair. Just for Bob -- Bob, inventory just came in at 174; others have been a bit all over the place with the divestitures and acquisitions. But is this sort of the level that you want to operate at? Or do you have sort of the inventory base target going forward?
Bob McMullan - SVP and CFO
Tory, I didn't get all the detail. Can you repeat that? The numbers faded out.
Tore Svanberg - Analyst
Yes, the inventory there is that 174. Is this the level that you want to operate at, or do you have a target for us?
Bob McMullan - SVP and CFO
No, we'll come down off that. So we have erred to the high side from our inventories to be optimistic in terms of gaining turns and shares and supporting customers. But endemically as the way we integrate the fabs into Lowell, inventories will come down.
Tore Svanberg - Analyst
Very good. And your DSOs were unusually low this quarter. I'm not saying that's a problem, but was this just a very linear quarter? Or anything else going on there?
Bob McMullan - SVP and CFO
I don't know what to say. Thank you. (laughter) We worked the balance sheet pretty hard. We understood where the inventory was going to be and planned for it that way. And we've been pushing the collection process.
Tore Svanberg - Analyst
Sounds good. Very good, thank you.
Bob McMullan - SVP and CFO
Welcome.
Operator
Dave King, B. Riley.
Dave King - Analyst
Thank you. Good afternoon. First question is regarding your network business. It was up, looks like, 16% sequentially. Just wondering what the organic growth was?
John Croteau - President and CEO
Yes, the two huge growth drivers were lasers, across both PON as well as backhaul. And some -- absolutely some growth beginning to contribute from data center, the 25G stuff beginning to ship in for data centers.
And then the metro/long-haul stuff. We're feeding into the deployments -- you know, AT&T, Verizon, China Mobile, China Unicom. So the metro buildouts are a big deal for us in terms of driving growth. So I'd say those were the two primary driver areas.
Dave King - Analyst
Right. Actually, the question was, what was the organic growth? Excluding that acquisition in the December quarter, sequentially.
John Croteau - President and CEO
Yes --
Dave King - Analyst
Is it up about -- still double digits, or --?
Bob McMullan - SVP and CFO
Close to double digits.
Dave King - Analyst
Okay.
John Croteau - President and CEO
Close to double digits. And one thing that I'll point out that's problematic is we don't have an apples-to-apples situation there. We described last quarter -- so FiBest was a customer of ours. So as a company coming into it as a business unit, the revenue was not incremental, because we lose the revenue claim into, and it becomes -- and it shows up as COGS improvement.
So it's impossible to do an apples-to-apples mathematical addition. So I -- off the top of my head, I can't answer the question. But I can guarantee you it's double-digit organic growth.
Dave King - Analyst
Got it, got it.
John Croteau - President and CEO
I know just from the fact that the lasers in the metro/long-haul stuff were very strong.
Dave King - Analyst
Right. And then regarding your comments about backhaul and PON, is that pretty much -- you're referring to China? Or is that sort of global?
John Croteau - President and CEO
So all of this stuff at this point is built in China to service global demand. So if you talk about transactional sales, it's very heavily if not entirely China, whether it's Alcatel-Lucent demand, or Cisco demand, or whoever you're talking about. Transactional sales are in China for production.
But I would say on the backhaul side it's a mobile demand situation. It's not just the China buildout. And likewise, China does have a buildout for fiber-to-the-home, but it is not the majority of the share of global buildouts for fiber-to-the-home. So certainly China has contribution, but it's truly global.
Dave King - Analyst
Got it. And my last question is regarding -- you talked about AT&T and Verizon. Any movements out of the Verizon supply chain since last week's strike?
Bob McMullan - SVP and CFO
So remember, we are on the starting point of the supply chain. So we have seen activity that we believe is related to -- strongly related to Verizon. But it is not impacting -- we see no slowdown of that demand process as we sit here today.
Dave King - Analyst
Got it. Thank you very much.
John Croteau - President and CEO
You're welcome.
