Nortel Carries 40G Across 12,000km Submarine Cable

Nortel has demonstrated 40G optical transmission across Reliance Globalcom's Atlantic cable FA1.

The recently completed trial was conducted over a 6000 km submarine segment between the United Kingdom and the U.S. During the trials Nortel equipment was simply added to both ends of the third-party submarine cable, with Nortel able to demonstrate the ability to provide over two times the bandwidth capacity without the need to replace or upgrade the submarine cable or undersea repeaters.  In addition, the FA-1 cable was looped back to create a continuous 12,000 km segment.  The result is believed to be the longest 40G result yet achieved.
