100 gigabits per second service to meet businesses’ increasing bandwidth demands and to deliver lower latencies, higher uptimes and seamless scalability

Tata Communications, a leading provider of A New World of Communications, today announces 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 upgrade will deliver bandwidth and provide flexibility to carriers and enterprises to scale their network seamlessly and meet their increasing capacity demands, driven by the use of cloud computing and mobile devices, as well as other high-bandwidth services including music / HD video downloading and social networking applications. It will be instrumental in increasing carrier network performance through consolidation of transport traffic.

“The move to 100G coherent technology on our TGN-Atlantic cable system demonstrates our leadership in global network infrastructure,” says Genius Wong, Senior Vice President of Global Network Services at Tata Communications. “Based on Ciena’s GeoMesh, this major deployment will bring maximum bandwidth, lower latencies, higher uptimes and seamless scalability for carriers and enterprises, today and in the future.”

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 TGN IP Transit Network (AS6453) makes up 20% of the world’s internet routes and carries 4,200 Petabits of traffic per month on its Internet backbone. Ciena's WaveLogic coherent receiver technology enables unobtrusive 40G/100G upgrades to existing submarine networks with only the addition of new terminal equipment, significantly extending the life of existing cable plants and further lengthening their lifespans into the future.

The TGN-A will also be equipped with Ciena’s GeoMesh solution. “Our GeoMesh solution is designed to help operators like Tata Communications simplify their global networks by removing traditional network seams that inefficiently linked submarine networks to terrestrial networks,” says Ed McCormack, Vice President and General Manager, Submarine Systems at Ciena. “GeoMesh makes networks more cost-effective, reliable, and lower in latency.”

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.

Tata Communications’ global connectivity services are built on the world’s largest and most advanced global subsea cable network, which enables carriers and enterprises to connect almost anywhere in the world. The cable network boasts significant depth in the key emerging markets including Asia, Middle East and Africa.

Ciena is a pioneer in coherent optical technology. It offered the industry’s first commercially-available systems, with coherent 40G deployed since 2008 and coherent 100G since 2009. To date, Ciena has shipped 20,000 coherent 40G/100G line interfaces to more than 100 customers across the globe, with more than 20 million coherent kilometres deployed.
