Tata Communications announced the launch of 100 gigabits per second-enabled services on its TGN-Atlantic (TGN-A) subsea cable system from New York to London. Using Ciena's GeoMesh networking solution (based on its market-leading 6500 Packet-Optical Platform powered by WaveLogic 3 coherent optical processors and optical bypass), Tata Communications is upgrading its TGN-A submarine cable to 100G -- the first on its global submarine network. The TGN-A will also be equipped with Ciena's GeoMesh solution.

The implementation will pave the way for further upgrades leading to multifold increase in bandwidth availability across Tata Communications' Global Network (TGN), which consists of 210,000 kilometres of terrestrial and subsea network fibre, reaching countries representing 99.7% of the world's GDP. The first phase of the deployment will bring 100G capability to the New York-London route, expected to be in full service during the first half of 2013.
