Home > Submarine communications cable


 Contents
A submarine communications cable is a cable laid beneath the sea to carry telecommunications between countries.

The first submarine communications cables carried telegraphy traffic. Subsequent generations of cables carried first telephony traffic, then data communications traffic. All modern cables use fiber optic technology to carry digital payloads, which are then used to carry telephone traffic as well as Internet and private data traffic.

As of 2002, submarine cables link all the world's continents except Antarctica.

It is designed to factor out general communications cable issues from transatlantic / telephone / telegraph special cases

1 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 1920sCenturies: 19th century 20th century 21st century Decades: 1870s 1880s 1890s 1900s 1910s 1920s 1930s 1940s 1950s 1960s 1970s Years: 1920 1921 1922 1923 1924 1925 1926 1927 1928 1929 Events and trends Technology John Logie Baird invents the first working t it needed a number of technological advances that did not arrive until the 1940sCenturies: 19th century 20th century 21st century Decades: 1890s 1900s 1910s 1920s 1930s 1940s 1950s 1960s 1970s 1980s 1990s Years: 1940 1941 1942 1943 1944 1945 1946 1947 1948 1949 Events and trends Technology First nuclear bomb First cruise missile, the to be practical.
