All About Calix

These days, even companies with lots of promise are choosing to remain stealthy, given the uncertain economic conditions.

Take Calix Networks, which was founded two years ago this month but remains officially in stealth mode. The company, which is targeting the access network, is believed to have nearly 300 employess and has raised more than $100 million in venture capital, but it's in no rush to tell the world what it's doing.

Sources familiar with its plans say Calix is focused on eliminating the bandwidth bottleneck between the metropolitan area networks (MANs) surrounding cities and the businesses and residences within the cities. The product is targeted toward incumbent carriers that want to migrate to fiber-based services but need to protect their legacy telephone business at the same time.

"They're building a local loop box that is very scaleable and flexible," says one source close to Calix. "Their thinking is that what has been good for the metropolitan area networks is good for the access network. You can expect that it will be much more than an optical transport system for the access space. It will have a high-speed backplane and use advanced ASICs so carriers will be able to add new data services as soon as subscribers demand them."

The quiet startup has gained notoriety because of its influential backers, including the contract manufacturer Flextronics International (Nasdaq: FLEX) and Carl Russo, vice president of optical strategy at Cisco Systems Inc. and the former CEO of Cerent. Calix is located in Sonoma county, Calif., the home base of a number of pioneering optical companies, including Advanced Fibre Communications Inc. (Nasdaq: AFCI) and Cerent (which was purchased by Cisco).

Calix's vice president of optical products, Tom Corker, wrote an article for Lightwave magazine in July that gave some glimpse into the company's thinking and product plans. Corker's article describes the need for a box built with a line card and chassis architecture that combines several transport and access technologies and could speed the rollout of fiber-based services to businesses and residences.

Like a digital loop carrier (DLC), the box Corker describes would provide copper connections that fan out from a telephone central office or controlled environment vault. Along with digital subscriber line access multiplexer (DSLAM) functions, Corker writes, a new class of optical access platforms should provide add/drop multiplexing for Sonet, DWDM, and gigabit Ethernet services. The box should also use embedded edge switching, routing, and digital crossconnect functions working together to "process, groom, and manage any combination of TDM, cell, and packet traffic, including ATM, frame relay, and IP/MPLS."

Light Reading's director of research, Scott Clavenna, has also opined on what kind of access box carriers need right now, noting that Calix's box appears to be the most flexible and to support the broadest range of applications (see Dig This).

Such product descriptions, while not technically specific, do at least establish that Calix is not a direct competitor with Cisco's Sonet multiplexing equipment based on the Cerent acquisition (Nasdaq: CSCO), as had been previously assumed (see Theft Case Shines a Light on Calix ).

Instead of Cisco, Calix's competitors appear to include broadband loop carriers such as Occam Networks and Catena Networks, a startup whose product integrates DSLAM, DLC, and media gateway functions while eliminating the need for residential integrated access devices.

Other Calix competitors would include optical access router maker Xalted Networks Inc. and next-generation digital loop carrier makers such as Alcatel SA (NYSE: ALA; Paris: CGEP:PA), Marconi Communications PLC (Nasdaq/London: MONI), Advanced Fibre Communications Inc. (Nasdaq: AFCI), Lucent Technologies Inc. (NYSE: LU), and Integral Access Inc.

So, what about that burn rate? Research points to the company being well funded. As of December 31, 2000, Calix had gross assets, including cash, inventories, and loans to shareholders, totaling $74,202,439, according to documents obtained by Light Reading. The company took another large round of funding in March, though company officials will not confirm the amount. According to a June 15 Wall Street Journal article that Calix posts on its Website, the company has raised $158 million in funding, employs 275 workers, and carried a valuation of $525 million earlier this year

Assuming the company has between 200 and 300 employees, its burn rate would be between $20 million and $40 million per year, to judge from industry averages.

Calix's board members include Michael Hatfield, Calix's president and CEO; Ajaib Bhadare, one of Cerent Corp.'s cofounders; Cisco's Russo; and Paul Ferris, a partner at Azure Capital Management.

The company's investors include Azure Capital Partners, Flextronics, Integral Capital Partners, Meritech Capital, Michael Dell's MSD Capital Partners, Pivotal Asset Management, Redpoint Ventures, and several individuals, including Russo.

The company's managers hail from digital loop carrier makers such as Advanced Fibre Communications and Optilink Corp. (Optilink was bought by DSC Communications in 1990; DSC was bought by Alcatel in 1998). Most of the top managers have also worked at Cerent. A former engineer in Alcatel's Litespan division, Jason Dove, is said to the primary architect of the Calix product.

Calix declined to comment for this article.

Good for them and their surviving competitors.


The old competitor list has changed somewhat now that a few years have passed.

True and what failed before with companies with no real value proposition will also be true again.

re: All About Calix

Yea, I agree.

Now that they are public, and have set the bar pretty high for themselves to attain profitability with forward margins of ~40% for platforms like the E7, we'll see.

I'm wondering if the E7 truly is an all-IP platform or is it just an extension of the C7 with an ATM backbone?

This coulds have implications for their ability (or lack thereof)) to really attain those margins.

re: All About Calix


Thanks for the perspective...


So is the E7 anywhere near the functional equivalent of the Occam product?

Is it a stand alone product? 

Or must it be coupled with a C7 platform?

Makes me wonder how they will EVER make those higher margins they were crowing about during the IPO...

Seems they'd have to almost cherry pick only the largest deployments for the best scale and margins...

re: All About Calix


There margin issues are a LOT simpler than that.  Traditional Access Margins are in the 30s (go back to DSC days to see this).  Only one company has built a traditional access company (Adtran is a niche player) that has margins above 40% - AFC.

On top of all of that the scale of the C7 does not match all the deployments that they go after.  If you look at their big customer (Century), they have a few large properties (example: Vegas) and the rest look like traditional IOC properties.  The C7 is too big for many of those applications, which is why Occam does so well in those smaller markets.  It fits the AFC replacement business better than Calix does.

Remember the C7 was targeted as a Litespan replacement, just the market evolved away from that as a possibility.

My understand of the E7 is that it is new.  And by all-IP, I believe you mean all Ethernet.  Many IP routers have switching models based around cell based concepts.

re: All About Calix


It is a standalone product as far as I know.  I am sure they are working on higher margins, but we shall see.

Big deployments tend to lead to lower margins.  One of the thing I am sure of is that Century prior to the acquisition got less discounts than Embarq.  How long do you think that lasted on the combined business?

My guess for overall margins, the way to get there is ONT cost reduction.

Please do not try and compare AFC Profitability with the Calix lack of profitability.

Earnings for AFC where very succesful EVEN before the Cerent cash windfall.

However AFC was a $200M company and profitable - plus it never took $500M of VC money to make a product - more like $20M.

Did you read this ?

Verizon will no longer seek new cities to roll out its FiOS TV service as the company nears the end of its $23 billion network upgrade project.

The New York telecommunications provider has wagered heavily that its bundle of faster Internet service and TV would give it an edge over its cable rivals, and has spent the last six years replacing much of its older, slower copper lines with faster fiber-optic ones.

re: All About Calix


Just for comparisons sake, I located an old 10-k of AFC at:



The financials start in earnest about 3/4 the way through the document.  Note this is the year that Cerent got bought, which accounts for the huge gain on the balance sheet.

Now, just for everyones memory this company was sold for $1.4B or so, with about $1B on the balance sheet or an enterprise value of $400M or so.

An April fools' joke.

I do have to admit that you had me going for a few picoseconds.
