TL;DR: In this article, a 107Gb/s field trial was conducted on a traffic carrying longhaul LambdaXtreme® transport platform over an active 504-km Verizon route in Florida thus proving upgradeability to 100 G of the Alcatel-Lucent 50GHz spaced ULH DWDM system.
Proceedings ArticleDOI
DWDM long haul network deployment for the Verizon GNI nationwide network
TL;DR: A 226 node, 128 channel Raman gain based DWDM system being deployed by Verizon GNI to create a nationwide automated optical network carrying 10 Gb/s traffic and offering 40 Gb-s traffic capability is presented.
Proceedings ArticleDOI
Field trial of 107-Gb/s channel carrying live video traffic over 504 km in-service DWDM route
