Earlier this week Nortel Network Corp. unveiled a new 40 Gbps to 100 Gbps optical network system and has now kicked off a trial of the fast Internet equipment with Comcast Corp. Nortel's new optical technology allows carriers to scale to meet capacity demands, resulting from increased use of IPTV, Internet video, HD programming and mobile phone games. It's a revolutionary technology platform that allows fiber-optic cables, thinner than a human hair, to carry vast amounts of information. The current network speed is 10 Gbps, which can support 1000 HDTV channels simultaneously. By increasing that capacity to 40G, carriers can transmit four times the traffic over the same link and 10 times the traffic when evolving to 100G. Comcast will be the first operator to trial in a live environment a 100G wavelength on its existing network. The company will also maintain live 10G and 40G links. The trial will run in parallel over the same optical infrastructure that supports a combination of high definition or HD video, Internet and voice traffic. "As we continue to expand our cross-platform video, voice and data services, we need these types of innovative technologies from vendors like Nortel to support the rapid growth of new applications and services that run over our network," said John Schanz, executive VP of national engineering and technical operations for Comcast.
