TGN-Atlantic Cable Upgrades to 40G with Ciena

Tata Communications' TGN-Atlantic subsea cable system, which links New York to London, has launched 40 Gbps services following a network upgrade using Ciena's coherent optical technology. This marks the first deployment of 40G coherent optical technology on Tata Communications' global submarine network, which consists of over 200,000 kilometres of terrestrial network fibre and over 500,000 kilometres of subsea cable.


The TGN-Atlantic upgrade is based on Ciena's 6500 Packet-Optical Platform with 40G /100G coherent technology. Ciena's WaveLogic coherent receiver technology enables unobtrusive 40G / 100G upgrades to existing submarine networks with only the addition of new terminal equipment. The first phase of the deployment will bring the 40G capability to the New York - London route. In the second phase, this will be extended to Ashburn, Virginia and the rest of Europe. http://www.ciena.com
