History of submarine communications cables
The first submarine communications cable was a telegraph cable laid between England and France in August 1850 by the Anglo-French Telegraph Company. In 1852 a link laid by the Submarine Telegraph Company linked London to Paris for the first time.
The first transatlantic telegraph cable was laid in 1858 (Cyrus Field). It only operated for a month. Attempts in 1865 and 1866 were more successful but although a telephone cable was discussed from the 1920s it needed a number of technological advances that did not arrive until the 1940s to be practical.
TAT-1 (Transatlantic No. 1) was the first transatlantic telephone cable system. It was laid between Gallanach Bay, near Oban, Scotland and Clarenville, Newfoundland between 1955 and 1956. It was inaugurated on September 25 1956, initially carrying 36 telephone channels.
