  1. US seems to lag in Broadband speeds compared to some European and Korea, is the industry deliberately doing this for profits or is it just the way it is? I hope if they put their heads together and increase the speed it will be beneficial for everyone, we will see more progress.

    1. Its because the US is just so much bigger than any individual country in the EU and Korea. Broadband still hasn’t reach some areas of the US including most rural Texas.

  2. Still using 10 wavelenghts so the key here is the smart reordering algorithm.
    IMHO the real breakthrough will be with 100GE over a single wavelenght.

  4. This is not 100G… it is nearly impossible to reach 100% utilization on a multi-link transport path without adding an unacceptable amount of latency.

    It’s a vanity project. Big packets would break this configuration.

  5. vanity project…cute. It’s progress, folks. Laboratory settings, but progress. All steps in the right direction, in an effort to keep up.

  6. Bummer, I just finished re-wiring my house for gigE so it looks like I have another project for this weekend. Seriously though, Andrew is right, it’s just a vanity project but pretty cool nonetheless.

  7. hey, does this mean that sun is gonna bring project corona back to life and start selling us all cool smart cards that we can carry our ‘state’ around on to do stuff on dumb terminals calling into super servers via high speed connections? or will elgoog get there first 😉

  8. I would suggest it is as much progress as it is vanity…what did Om say 14 months since reporting on 10 GB/s networks…to me that is telling. I suppose we will see.
    I remember having a discussion with a Vivato engineer about 2 years ago at a customer conference, and he couldn’t help but laugh when I suggested home Internet speeds of 30+Mbps in 3 or 4 years, based on Metcalfe’s quote of a history of (an average) 50% increase a year in home connection speeds (remember this is pre-Fios/Lightspeed). Of course Vivato is out of business now and Internet speeds are quickly approaching that rate, and some at 30+ already. Yea, it’s just cool right now, but obviously this where things start, and apparently at ever quicker rates.

  9. While Infinera’s FPGA inverse-mux is cool, and Drew is one of the smartest guys around, the development is essentially a work-around for the inadequacy of the US telecom infrastructure.

    NTT has demonstrated 111Gbps per lambda in a field deployment over 160Km.

    Rather than heaping praise on a company that has a technology hack to circumvent the limitations of the carrier, why aren’t we heaping scorn on the carrier for being tardy in deploying cutting edge technology.


    [Each lambda was] modulated at 111 Gbps using the CSRZ-DQPSK

    160-km transmission was successfully achieved by amplifying these signals in newly developed optical amplifiers.

    NTT demonstrated in this experiment, for the first time, that it is possible to transmit 100 Gbps signal with forward error correction2 bytes and management overhead bytes of the OTN3 frame over long distances allowing the construction of large capacity optical networks that offer 10 Tbps or more.

  10. I believe that entrenched incumbent service providers deliberately slow the pace higher bandwidth consumer offerings. They certainly fall well behind the pace of Moore’s Law. Now, with VoIP and IPTV, and other potentially vastly profitable content on demand services that require more bandwidth in the home, we are starting to see higher speed DSL offerings, Fiber (FIOS) and other services.

    Those who own the networks do not innovate to deliver greater value to the consumer. Those who own the networks innovate, begrudgingly, in order to facilitate new revenue streams.

  11. Great. We go from discussing an interesting tech demonstration to pissing on American infrastructure.

    Those who own the networks can do whatever the f*ck they want with them. That’s what ownership is. If you don’t like it, move to North Korea.

  13. Well, I can’t think of any who have done what they want with their networks, and are actually still around, at least at their previous stature, or aren’t teetering from debt, but that’s right, they can do exactly what they want with them, at their own risk. I might not like what they have done, but I can’t see anything wrong with it. Who among them are NOT in business to make money?

  14. @chris writes “US seems to lag in Broadband speeds compared to some European and Korea, is the industry deliberately doing this for profits or is it just the way it is?”

    One of the main problems is that the US is very large and sparsley populated. Something like 90% of South Koreans (I assume you weren’t including North Korea. They just got hamburgers there, I’m certain they don’t have FTTP yet) are found in three relatively dense metro areas. Not only are there no Iowas to deal with, there’s not even a Connecticut or New Jersey.

    So no, there’s not a telecoms industry plot to somehow increase profits by NOT selling customers the services they want. There’s geography and demographics.

  15. Great to see all the comments here on the Infinera 100GbE demo. I must point out–this is not a vanity project, but a serious effort to develop and propose a solution that works for higher Ethernet speeds for the entire industry. We do believe the issue of very large packets can be dealt with effectively. See further details from my colleague Ted Sprague at http://www.infinerablog.com.

  16. Note, people should really follow the link to the Infinera site. I initially assumed this was link aggregation over 10x 10GE signals (see comment above) and I was wrong. This is a real 100GE solution, albeit proprietary, but with efforts underway to standardize it.

    What is VERY interesting is the high integration inherent in Infinera’s approach gives them a distinct advantage in this type of solution.

  17. More progressive noted today in 100Gig on LightReading. Like I said…every effort made, such as Infinera’s, is progress. So much for the vanity project/”big packets” theory, whatever that meant.
