EMEA submarine route upgraded with 40G optical networking tech

The managed network services provider Reliance Globalcom is set to upgrade a key cable route connecting Western Europe with the Middle East. Spanning more than 6,400 kilometres, the upgraded cable route will add 2.4 Terabits per second (Tbps) of capacity on a crucial submarine route that helps transport traffic between the Atlantic crossing and Asia portions of the company’s global submarine network.

The network will be upgraded with Ciena Corporation’s coherent 40G optical networking solution. This upgrade uses Ciena’s ActivFlex  6500 Packet-Optical Platform with 40G ultra long haul interfaces, and represents part of a strategy to increase the submarine network capacity without disrupting existing customer traffic or adding cost and complexity to the network.

Reliance Globalcom owns the world’s largest private undersea cable system that spans a total of 65,000 kilometres. When combined with the 190,000 kilometres of domestic fibre of its parent company, Reliance Communications, the global network connects 40 key business markets in India, the Middle East, Asia, Europe and the United States.

Ciena's 40/100G technology includes coherent optics, electronic dispersion compensation, and directionless and colourless ROADM functionality, enabling operators to increase the reach, capacity and flexibility of submarine networks.

Using innovative coherent receiver and dual polarisation phase shift key (DP PSK) modulation technology, submarine networks can be upgraded to 40G/100G with only the addition of new terminal equipment, significantly extending the life of existing cable plants.

“Even in uncertain economic times, delivering services to a global customer base of hundreds of service providers, thousands of enterprises and millions of consumers requires an agile, high-capacity network,” said Rory Cole, president and COO, Carrier & ISP, of Reliance Globalcom. “By adding Ciena’s 40G technology at our terminal stations, we increase our capacity by a factor of four with a clear, in-service path to 100G without disrupting existing customers, re-engineering our network or sending ships out to lay more fibre.”
