TAT-7

TAT-7 was the seventh transatlantic telephone cable, in operation from 1983 to 1994, initially carrying 4,000 3Khz telephone circuits between New Jersey, Unites States and Porthcurno in southwest England. It was owned by AT&T, British Telecom and France Telecom.[1]

Despite the fact that optical fiber had been invented in 1970, this cable was still using coaxial cable technology.
