Carrier services firm Tata Communications, which is part of the India-based Tata conglomerate, this week upgraded its trans-Atlantic TGN-Atlantic (TGN-A) subsea cable to run 100Gbps between New York and London.

The upgrade will bring increased bandwidth for businesses and carriers on both sides of the Atlantic to meet growing capacity demands driven by the increase in cloud computing and high-bandwidth services including music and HD video downloading.

Genius Wong, SVP of global network services at Tata, said the implementation will pave the way for further upgrades leading to multifold increase in bandwidth availability across Tata’s global network, which consists of 210,000 kilometres of terrestrial and subsea network fibre.

Tata claims to have the only fibre optic ring around the world, making up 20 per cent of the world’s internet routes and carrying 4,200Petabits of traffic per month on its internet backbone.

Tata tapped Ciena and its GeoMesh offering for the upgrade, including its 6500 Packet-Optical Platform powered by WaveLogic 3 coherent optical processors and optical bypass.

The first phase of the deployment will bring the 100G capability to the New York-London route and expected to be in full service during the first half of 2013.
