Invention of the Cable

A cable is a bundle of wires or thread-like fibres that carry electric current or light-pulses. Cables are used to distribute electric power and to transmit communication signals. They are also used to connect parts of various electronic devices like computers.

The first long-distance cable was developed by F. B. Morse in 1844. It worked between Washington and Baltimore. It was strung on wooden poles. Necks of broken bottles were used for insulation. In 1861, a cable link was set-up between California and East Coast.

Next came submarine cables in 1866. The scientists behind the development of ocean cables was a British physicist named James Thomson who was later given the title “Lord Kelvin”. Such a cable came to be laid between London and Simla in India in 1870 A.D.

Recently fibre-optic cables have been developed. The first such cable was put into operation in 1983 between New York and Washington.
