Transatlantic cable system upgraded to support OTN services and 100G

One of the leading operators in India is upgrading its transatlantic submarine network to address growing bandwidth demand. Reliance Globalcom is implementing the GeoMesh solution from network specialist Ciena to facilitate high-bandwidth services such as cloud computing and video along the transatlantic corridor.

The Indian operator owns and operates one of the world’s largest and most advanced private submarine networks spanning more than 73,000 kilometres. When combined with more than 200,000 kilometres of domestic fibre owned by its parent company, Reliance Communications, the combined global network connects over 40 key business markets across India, the Middle East, Asia, Europe, and the United States.

The GeoMesh solution is based on Ciena’s 6500 Packet-Optical Platform, itself powered by WaveLogic 3 coherent optical processors and optical bypass. It supports OTN-based client services from OTU2 (10G) to OTU4 (100G), and will allow Reliance to provide 100GbE services between continental points of presence.

“Terrestrial OTN-based networks continue to gain in popularity, primarily due to its numerous benefits over SONET/SDH and its support for optimised Ethernet transport. As terrestrial network adoption of OTN technology continues to increase, submarine networks interconnecting these land-based networks must support seamless handoff of these burgeoning new services”, said Ed McCormack, VP and GM of International Accounts and Submarine Systems at Ciena.

“The solution enables us to quickly and significantly increase the information carrying capacity across our critical FA-1 submarine cable network while eliminating complexity and latency along the critical corridor serving data centres in New York and Paris. We can also seamlessly merge our submarine and terrestrial networks together, from our New York PoP to our Paris PoP, which was not possible in the past”, added Punit Garg, President & CEO at Reliance Globalcom.
