Total length12.935 km[1]
Design capacity5.12 Tbps[1]
Date of first use2001[1]

The cable was operated by the American corporation Tyco International until it was acquired for 130 million US$[2] by India's Videsh Sanchar Nigam Limited (VSNL) in 2005. Since 2008 VSNL was rebranded as Tata Communications[3] and the cable was named TGN-A for Tata Global Network Atlantic.[4]

The cable system is constructed from two separate cables routed slightly differently, but both cables terminate in the same locality at each end. Each cable is constructed with 4 fibre pairs per cable, and each fibre pair supports 64 10 Gbit/s waves at construction, allowing for a total lit capacity (at construction) of 2 cables x 4 fibre pairs x 64 10 Gbit/s waves = 5.120 Tbit/s.
