Verizon Adds Nortel to Its 100G Club

Verizon Communications Inc. (NYSE: VZ) is certainly playing the field when it comes to checking out the potential of up-and-coming 100 Gbit/s optical gear.

Having already hooked up with Alcatel-Lucent (NYSE: ALU) and Nokia Networks for previous tests and trials, the giant operator today announced it has completed a field trial with Nortel Networks Ltd. , with signal quality at the heart of this particular demonstration. (See Verizon Goes Long(er) With 100-Gig and Verizon Keeps 100-Gig Promise.)

Verizon noted today that its latest 100 Gbit/s trial, across a 73 kilometer connection in Northeast Texas, "performed with better tolerance for signal distortion than typically found in today's standard wavelength of 10G. This is a significant next step toward the commercialization of 100G transmission." (See Verizon Does 100G With Nortel.)

In fact, the carrier noted that the trial, using Nortel's Optical Multiservice Edge 6500 platform, "demonstrated twice the tolerance for signal distortion" as 10 Gbit/s systems. Nortel attributes this quality gain to unspecified "advanced signal-processing [and signal-correcting] techniques that maintain sustained signal integrity despite significant polarization mode dispersion (PMD)."

Verizon noted that the trial traffic was transmitted error-free, and that "preserving the level of quality for high-speed traffic is important for such ultra-long-haul network strategies as mesh architecture."

Verizon is expected to provide further details of this trial and its 100 Gbit/s strategy today when the carrier's director of backbone network design, Glenn Wellbrock, delivers the opening keynote speech at Light Reading's Optical Expo 2008 event in Dallas.

News of the trial will come as a fillip to the Nortel optical team, which, despite having already made its mark with other 100 Gbit/s trials and being regarded as one of the leading optical R&D houses, finds itself in limbo as the company's management seeks a buyer for the business.

re: Verizon Adds Nortel to Its 100G Club N. Texas = Ole Worldcom Optical Lab Eh?

re: Verizon Adds Nortel to Its 100G Club This story has two ironies. One is the already mentioned fact that this feat was performed by a division currently on the block. What does that say about society's valuing optical tech and communications?

Secondly, why N. Texas. Huh ATT?

re: Verizon Adds Nortel to Its 100G Club Tell me more. Is an old WCOM lab the brains of VZ?

re: Verizon Adds Nortel to Its 100G Club wellbrock was in the mci-worldcom networking group, so there are probably a lot of similarities.

re: Verizon Adds Nortel to Its 100G Club 1) no, these guys are NOT old WorldCom guys. Only were worldcom for the short time from when Worldcom merged with MCI and when Worldcom flamed out and was re-organized and the key part that was MCI, became MCI again.

2) The reason it was done in North Texas was due to the unique nature of the MCI labs in Richardson. For many years, MCI labs there have been a truly world class facility. Able to test and develop solutions and contribute not just to MCI's network, but to fundamental standards work and interoperability testing that is later used by many in the industry. In MCI's labs there are two nice aspects. Literally all the test equipment and staff needed to do the work. And the nature of their test bed itself. They can do "lab testing" where spools of fiber and edfa's etc. are strung together to make a "link" test... but they can also do some really interesting real world testing. This lab has actual loops of deployed LIVE REVENUE bearing traffic and loops of unlit fiber in same trunks.. all circulating through the labs. In addition, the physical plant from the various iterations of MCI's growth have left MCI with virtually every kind of fiber located someplace in the loops in north texas. So, MCI can do lab testing, then "lab level" link testing, then testing on dark fibers in a "lit" trunk.. then testing on lit fibers...carrying traffic on other channels or wavelegths, but NOT live traffic of revenue paying customers, to testing interoperability on actual live fiber spans with the test traffic running on test wavelengths on same fibers as customer traffic.

this multi-layered test lab capability makes the MCI labs in Richardson one of the more unique labs of it's kind and it is quite powerful advantage for MCI being able to adopt technology more quickly and more flexibly than ATT or Sprint.

Hope this helps explain why the trail was in North Texas. Note, I was not involved in the trial and do not work for MCI. But have long history working with MCI, and Worldcom... both from before they were merged.. and with Verizon, and SBC, et al

re: Verizon Adds Nortel to Its 100G Club Nope, not an old WorldCom lab. Take it from someone who knows QUITE well.. .this is an old MCI lab. the flagship MCI lab from before the worldcom merger. The Worldcom labs were in the suburbs of Houston.

fact. Not speculation.

re: Verizon Adds Nortel to Its 100G Club
Just for completeness, the Houston Labs were actually old Wiltel labs (the first time Williams did Telecom). I believe they opened around 1990. MCI's labs were around for quite a long time before that. I remember one visit I had there where the offices were in the center and all had glass walls.

re: Verizon Adds Nortel to Its 100G Club Actually WilTel did not have much in Houston, everything was in Tulsa, OK. The big Williams presence was on the oil/gas side when they bought Transco (the same pipeline one of their major routes runs along). When Williams Companies restarted their fiber business as William's Communications, they kicked Worldcomm out of the BOK Tower in downtown Tulsa. Worldcomm built a facility in a northern suburb of Tulsa. I will say I have no clue what, if any, presence Worldcomm has in Houston from their LDDS days, but none of my friends in the Tulsa labs every mentioned it.

re: Verizon Adds Nortel to Its 100G Club Thanks for the clarification Sail.

When I was there at 400, which was not often, everything already had WCOM on it. I spent more time in Herndon where there was a much more clearer seperation of aquired groups, well at least one - hehe UUNET, remember Ash Wednesday and the T-shirts.

And during the MCI days I was covering Bell Atlantic.

re: Verizon Adds Nortel to Its 100G Club Thank you for the info, sailboat. As much as I grind my teeth over telcos, it is a tribute to VZ management to keep such as lab up to date, that is if they have. Perhaps this lab is behind the FiOS architecture.
