TAT-12/13

TAT-12/13 is a ring cable system consisting of the 12th and 13th consortia transatlantic telephone cables, in operation from 1996, initially carrying 2 × 5 Gbit/s.

This was the first TAT cable to use a ring structure, involving two stretches of cable across the ocean floor, which explains why two numbers (12 and 13) were used. All later cables also use a ring structure, but only use one number (TAT-14 etc.). The cable connected between Long Island (at Shirley, New York, USA and Bellport, New York, USA); Porthcurno, UK; Bude, UK; and Penmarch, France.

The TAT-12/13 consortia removed the cable from normal commercial service on 31 December 2008.
