TGN-Eurasia, or TGN-EA, is a 9,280 km cable system linking Mumbai in India with Marseille in France, passing through Egypt, with a branching unit to Jeddah, Saudi Arabia. TGN-EA offers route diversity through a terrestrial route in Egypt without touching the Alexandria CLS & the Suez CLS.
TGN-EA cable system consists of two fiber, with an initial design capacity upto 1.28 Tbps, and one fiber pair express route between Mumbai and Marseille.
In Egypt, TGN-EA terrestrial paths run between the Abu Talat CLS and the Zafarana CLS. Tata Communications partners with Telecom Egypt for TGN-EA landing at the Abu Talat CLS and the Zafarana CLS and terrestrial paths between the cable landing stations, dropping TGN-EA capacity in Egypt for connectivity into Egypt and also extending the reach to countries like Libya, Cyprus, Sudan, Jordan, Syria etc through Telecom Egypt.
Tata Communications also partners with Mobily and other operaters for TGN-EA branching into Jeddah, Saudi Arabia, extending the TGN-EA cable systems into the Middle East, and establishing the TGN-Gulf cable system.
TGN-EA forms a part of Tata Global Network's (TGN) together with other cable systems like TIC, TGN Intra-Asia, TGN Pacific, TGN Atlantic and European ring, enables PoP to PoP connectivity allowing customers to terminate capacity at Mumbai or at Marseille and also at other TGN PoPs
TGN-EA cable system offers low latency routes, with round-trip-delay (RTD) of 92 ms between Mumbai and Marseille, 52 ms between Mumbai and Jeddah, 52 ms between Marseille and Jeddah.
TGN-EA cable system is a private cable owned by Tata Communications and supplied by SubCom. TGN-EA cable system was ready for service in April 2012.
TGN-EA and SEACOM are a common cable in some segments. In addition to its East African portion, SEACOM has two fiber pairs between Egypt and India, on a common cable with TGN-EA. TGN-EA represents another two fiber pairs from Egypt to India and the branch to Jeddah (i.e., TGN-Gulf). Both SEACOM and TGN-EA have one fiber pair on TE North for connectivity across Egypt to Europe.
