100G Watch: OFC/NFOEC Warmup

At OFC/NFOEC next week, 100-Gbit/s optics will become an even hotter topic than they've been in the past several months. Here's a look at where some of the discussion has been headed so far, from the service provider perspective.

  • When Verizon Communications Inc. (NYSE: VZ) starts deploying new fiber routes, they'll be built with 100-Gbit/s transmission in mind, Glenn Wellbrock tells analyst Roy Rubenstein on the Gazettabyte blog.

    Wellbrock, director of backbone network design, expects those build-outs to start by 2012, possibly earlier. But here's the catch: "100 Gbit/s" here implies coherent detection, which in turn means Verizon Business won't use any optically based dispersion compensation. Dispersion will be corrected using the receiver's electronics.

    That's likely to be the norm for long-haul 100-Gbit/s links, anyway. But it means that Verizon will insist on coherent detection for 40-Gbit/s traffic, too, on those new fiber routes.

  • No one expects the big customers to stop rallying for speeds beyond 100 Gbit/s. Donn Lee of Facebook has been doing so for months, going to various industry conferences to say his company needs 100-Gbit/s Ethernet already. Light Reading reported on his appearance at a seminar organized by The Ethernet Alliance , where his talk touched off a discussion about Terabit Ethernet. (See Facebook: Yes, We Need 100-GigE.)

    He reprised that talk in early February and brought up the topic again a few weeks ago, at the Ethernet Technology Summit in San Jose, Calif.

  • Along possibly similar lines, OFC/NFOEC's Service Provider Summit will be keynoted by Vijay Gill, senior manager of engineering and architecture at Google (Nasdaq: GOOG). The subject is "Building Very Large-Scale Computer Infrastructure," and it's ostensibly about the computers themselves -- although it's a good bet 100-Gbit/s Ethernet, or some bigger number, will get a mention.

    Other recent bits and pieces from the 100-Gbit/s world:

    I would love to see 100G be profitable for the users, box manufacturers and component manufacturers.


    I suspect it will be profitable for 1, maybe 2 of those.

    Actually, what if Verizon *is* the second!  That is, the New York Stock Exchange or some other financial entity could be 1st to deploy (that is, deploy fully standards-based, serial, 1-wavelength, 100GigE with OIF-compliant long-haul optics... did i leave out any qualifiers there?)


    I have no evidence that this is going to happen; just tossing the idea out there


    Other reasonable candidates: Comcast, Telstra, DT, SurfNet....  Qwest has talked about 100Gig with AlcaLu but I doubt they'd be first or second to deploy it.

    re: 100G Watch: OFC/NFOEC Warmup

    That's how I see it too.


    I presume we're looking at the same two...  I'm wondering what it will take to make 100G profitable for the components vendors.

    Who will 100GE's second customer be?

    re: 100G Watch: OFC/NFOEC Warmup

    Do you have access to estimates for 100GE adoption in long reach (10, 40km) and short reach formats over the next few years?


    I expect that the numbers will need to be very high for component mfgs to make money.

    <div>Not too many years ago you could say the same thing about 10Gig, and a few years before that, about 1Gig. Now they build 1Gig into PCs and put 10Gig switches in the office.

    10G was severly skewed by the bubble.&nbsp; 40G would be a better comparison.


    Anyone want to argue that 40G is wonderfully profitable for the whole chain?&nbsp; How many years since the first announcements?

    q (2010): how do we make 100g profitable for component vendors?


    a: by letting them make some money off of the 40g first and not upgrading to 100g yet.


    &nbsp;


    q (2012): how do we make 400g profitable for component vendors?


    a: by letting them make some money off of the 100g which they introduced last year.


    &nbsp;


    q (2014): how do we make 1t profitable for component vendors?


    a: irrelevant, there are no component vendors left to innovate since they took a bath on the ever-changing requirements.

    Now we still "only" have 1Gig into PCs. And some people talk about a need for 100GE for switches, although I haven't seen any purchase orders.


    For comparison, Princeton University just recently passed the 1Gb internet utilization mark. Live graphs at: http://www.net.princeton.edu/
