Verizon Adds Nortel to Its 100G Club
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.
