Avago’s Interesting Demos at OFC/NFOEC

By Lisa Huff

As always, the top transceiver manufacturers were represented at OFC, but of the top three datacom transceiver providers, Avago Technologies stood out to me. They had two significant demonstrations:

1. Connecting a 40GBASE-SR4 Ethernet port using its QSFP+ to four standard 10GBASE-SR Ethernet ports with its SFP+ modules. On the surface, this seems pretty easy to do, until you realize that the specifications for the transmitters and receivers in these devices have are very different. The 10G devices could easily overpower the 40G receiver if it’s not designed to handle the higher power. Avago has solved this issue with its parts and hopes to be able to be interoperable with anyone’s transceivers in the near future.

2. A VCSEL-based 25G short-wavelength SFP+ working prototype. At first I was puzzled about this because I couldn’t figure out the application. Well, it turns out there really is none for the 25G part, yet, but showing that it could be done makes you realize that 32G Fibre Channel applications using the SFP+ may not be as far-fetched as we think. And, perhaps we can get a 100GBASE-SR4 (4x25G that isn't in the IEEE standard yet) solution soon.

Stay tuned for more on other developments announced or demonstrated at OFC/NFOEC.

Thoughts on OFC/NFOEC

By Lisa Huff

I’ve never been enamored with Los Angeles, but when OFC/NFOEC decides to go there, I really have no choice but to follow them. OFC/NFOEC is the premier optical components conference and is starting to move its way up the food chain again. Those of us who have been in the industry since before 2000 know that equipment manufacturers and service providers were regularly a part of OFC. But after 2000, this changed and the optical value chain was split – components relegated to OFC and/or NFOEC (until they combined into one), equipment manufacturers concentrating on Interop and Supercom and service providers opting for Supercomm. Now, Supercomm has closed its doors and Interop has become more and more software-centric. So both OEMs and service providers are looking for a trade show of value and they may have found it in OFC/NFOEC.

Notable communications equipment OFC/NFOEC exhibitors this year were ADVA, Ciena, Cisco, Fujitsu, Hitachi, Huawei, Infinera, Juniper, Mellanox Technolgies, Nokia Siemens Networks and Optelian. Many others gave speeches including Alcatel-Lucent, ADVA, Brocade, Ciena, Cisco, Cray, Force10 Networks, Fujitsu, Hewlett Packard, IBM, Infinera, Juniper, Nokia Siemens Networks and SunLabs/Oracle. Service providers participated by way of technical and business presentations as well – among them were AT&T, Deutsche Telecom, NTT and Verizon.

End users of networking equipment even showed up – NYSE Euronext, USA provided the plenary speaker for the Service Provider Summit and Facebook and Google again told us how much more bandwidth they need – Terabit Ethernet. There was an entire afternoon dedicated to large data center business issues at The Optical Business Forum, which included speakers from Abovenet, Allied Fiber, CENX, Equinix, Juniper, PacketExchange, Verizon, XO Communications Zayo Bandwidth and Zayo Networks.

So this seems to be a transition year for OFC/NFOEC where it has started to include more practical programming to expand its audience into data communications, data centers and up the value chain with equipment manufacturers and service providers. It appears to be working too, because the attendance was up by all accounts.

I’ll review some exciting new developments by systems and components suppliers in future posts.

Ethernet Technology Summit and OFC/NFOEC Events

By Lisa Huff

The next few weeks I’ll be very busy. First I’ll be chairing Session 105 (Ethernet Chipsets/Components) at the Ethernet Technology Summit. While most of the conference is about R&D projects, I’ve chosen to focus my short presentation on current opportunities for components suppliers.

In March, I’ll be heading to OFC/NFOEC 2011. There I have three different sessions I’m involved in. My short course on “Data Center Cabling – Transitioning from Copper to Fiber” will be held Monday morning. A short excerpt of this short course can be accessed through an archived Webinar I did recently. Monday afternoon I’ll be participating in the Computercom Symposium by presenting “The State of the Short-Reach Optics Market.” On Tuesday, the kick-off of the Optical Business Forum (see previous post for details) will take place and I’ll be moderating the Carrier Ethernet Exchanges session.

Come see us in Santa Clara this week or Los Angeles the week of March 7^th.

The Optical Business Forum

By Lisa Huff

I've got a number of events coming up, including the short course on data center cabling I'll be teaching at OFC/NFOEC.   Also wanted to let you know about The Optical Business Forum I've been working on for OFC, which will incorporate many of the data center technologies I've written about here.

This year's Optical Business Forum will be the first in what we’re hoping will be a yearly affair covering the most important topics in the area of optical transport for business communications. This year’s summit will be held right on the exhibit floor and consists of a keynote address on High-Bandwidth Ethernet Services by Rajiv Datta, Senior Vice President and Chief Technology Officer of AboveNet Inc. Following the keynote are three focused sessions:

1. Who is Buying Optical Bandwidth Services?
2. The Economics & Business Case for Connecting Data Centers
3. Carrier Ethernet Exchanges

The program includes speakers from AboveNet, Allied Fiber, CENX, Equinix, Juniper Networks, Packet Exchange, Telx Ethernet Exchange, Verizon Digital Media Services, XO Communications, Zayo Fiber Solutions and zColo. Moderators include Craig Clausen from NPRG, Michael Howard from Infonetics and myself.

Join us at OFC/NFOEC and hear what you’re customers’ customers are saying.

Optical Interconnection Players Strengthening Their Businesses

By Lisa Huff

Molex just purchased Luxtera’s AOC business completing the circle that all the other optical interconnect players started. During the telecom bust in the early 2000’s, Amphenol, FCI, Molex and Tyco Electronics all either de-emphasized their optical interconnect businesses or exited them all together. Now, they have all re-entered. Why?

While they are all working on more high-speed copper solutions like the one Tyco showed for 25G and beyond at SC10, I beleive they also see the writing on the wall. While they won’t admit it, I think they know that beyond 100G copper cable interconnects may have FINALLY reached the end of their useful life. At 40G and 100G, for example, there is still no twisted-pair solution and the direct-attach copper can only reach about 7m reliably.

It has been interesting watching the choices these traditional connector companies have made:

• Amphenol: It never exited the optical interconnect business, but left the transceiver products to Avago, Finisar, JDSU and others until recently. It has a stronghold on the short-reach copper direct-attach market so has inroads at customers for its AOCs and modules.
• FCI: Exited the optics business entirely for a few years but then started again from scratch and subsequently purchased MergeOptics in February 2010. MergeOptics is what was left of Infineon Technologies and still has strong technical abilities in short-reach products. It also has the building blocks to provide all-optical interconnects all the way from the chip (see my previous posts on MergeOptics). They can provide both AOCs and transceiver modules so have the ability to cover all high-speed markets in InfiniBand, Ethernet and Fibre Channel.
• Molex: Purchased Luxtera’s AOC business recently. So while FCI and Tyco are stressing short-wavelength technologies, Molex has turned to custom long-wavelength ones. Luxtera’s technology is based on 1490nm devices, which really doesn’t matter if you’re purchasing an AOC, but will matter if you want transceiver modules. According to company representatives, they will eventually get back into supplying transceiver modules, but there has been no evidence of this as of yet. Perhaps the possession of Luxtera AOCs will prompt this.
• Tyco Electronics: Tyco exited the transceiver business in the early 2000’s, but still had a very active fiber-optic interconnect business – especially for premise wiring (AMP NETCONNECT). It acquired Zarlink Semiconductor’s optical products group in May 2010. Zarlink is on the forefront of parallel-optics technology and was one of the first to introduce AOCs. It does not appear that Tyco intends to supply optical transceiver modules again.

I would never bet against copper re-inventing itself in order to meet the demands of future high-speed networks, but with optical 10G dominating the market currently and 40/100G optical products starting to emerge, it will be an uphill battle for copper solutions to gain traction. And beyond 100G, all bets are off. I’m thinking that these companies are reaching the same conclusions and that if they don’t add optical capabilities soon, they may render themselves obsolete within the next ten years or so. That's not to say that there won't be a vibrant businesses in both copper structured cabling and interconnects over the next ten years - there will be. But I think that R&D dollars will be better spent on optical interconnect technologies rather than trying to figure out how to run 25G signals using copper interconnects (including backplanes.) Or how to convince end-user customers in the US that a shielded structured cabling solution for 40G is better than a short-reach optical one because it will be cheaper - but at what cost to power, cooling and space?

What do you think? I'd love to hear your thoughts.

Old Data Centers Never Die

From ZDNet:

>>>Given the nature of JetBlue’s operations there, this datacenter facility had to be fully redundant on all levels, so there had been a considerable investment in the infrastructure of the facility to allow for 24/7 operations with high availability. But what do you do with this kind of facility when you no longer need it (which is not the same question as deciding if the facility has reached its end of life).

Enter Webair, a NY -based hosting provider that was looking to expand their operations. Today, less than 16 months after JetBlue made the decision to move out, Webair announced that they have opened up the facility as their new flagship datacenter  and executive headquarters, basing their Network Operations Center in the new (to them) facility which they have dubbed “NY1″.

Returns on Capital Expenditures vs. Capex Reductions

By David Gross

Just about every IT, networking, power, and cooling vendor serving this industry promises to both "reduce capex and opex".   But these goals are often meaningless, especially in the case of capital budgets, which often require board approval, and are set for the year.   Moreover, the number one objective of a capital investment is to get the highest possible return, as measured by IRR, not to spend less than you did during the last upgrade cycle. And in the case of opex, it's very easy, and very common, for salespeople to make spreadsheets showing big opex reductions that are not always achievable in practice, especially when most data centers are already very capital-intensive and highly automated.

Far more attention getting than droning on about opex, capex, ROI, and TCO like the herd, is to focus on more specific financial metrics that your product can improve upon.   IRR and NPV are good places to start.  Because most sales presentations confuse payback period with ROI, have no time value of money, and do a poor job showing tradeoffs, they have limited credibility.   IRR, which in my experience is known by some, but not all sales and marketing people, is the most important metric for any capital investment.    While it might take some education to explain what it represents to some buyers, if all the community college students taking introductory finance courses can learn it, I'm sure the CIO you're selling to can as well.
