TGN-Atlantic

TGN-Atlantic is a 13,000 km transatlantic submarine cable system linking the United States and the United Kingdom. TGN-Atlantic was ready for service in June 2001.

The TGN-Atlantic cable system is now privately owned and operated by Tata Communications.

The TGN-Atlantic cable system was originally invested and built by Tyco International, as part of its Tyco Global Network. In 2000, Tyco International announced to design, build, operate and maintain its own global undersea network, the Tyco Global Network (TGN), including TGN-Atlantic, TGN-Pacific, and TGN Europe-Asia, etc.

In 2005, Indian VSNL acquired Tyco Global Network (TGN) for $130 million.  In 2008, VSNL was rebranded as Tata Communications.

The TGN-Atlantic cable system consists of two separate cables routed slightly differently, but both cables landing at the same cable landing stations in the US and the UK:

  • Wall Township, New Jersey, the United States
  • Highbridge, Somerset, the United Kingdom

Each of the TGN-Atlantic cables has 4 fibre pairs, initially designed with 64x10Gbps DWDM technology, for a total system capacity of 5.12 Tbps.

The TGN-Atlantic cable system was upgraded to 40Gbps and 100G DWDM technology with Ciena's solutions, respectively in 2011 and 2013.
