Cable

Sometimes Roman tightrope walkers stretched cables between the tops of two neighboring hills and performed comic dances and pantomimes while crossing.

American businessman and financier Cyrus West Field  and his colleagues completed the first transatlantic telegraph cable in 1858. It crossed the Atlantic Ocean from Valentia Island in Ireland to Heart's Content, Newfoundland and Labrador, Canada.

 U.S. President James Buchanan inaugurated the new transatlantic telegraph cable by exchanging greetings with Queen Victoria of the United Kingdom.

In an experiment requiring nothing more complicated than two buckets, a tap and some water, the Irish scientist John Tyndall in 1870 observed that a flow of water could channel sunlight. Fibre optics – tubes of glass or plastic capable of transmitting signals much more efficiently than traditional metal wire – operate under the same principles and were perfected by Charles Kao and George Hockham in 1966.

The first cable across the Pacific Ocean was spliced between Honolulu, Midway, Guam and Manila in 1903.

Ferrets were used to lay the TV cable for use during the broadcast of the festivities of Prince Charles and Lady Diana Spencer's wedding in the Royal parks.

The longest cable in the world is the SEA-ME-WE-3, which runs from Western Europe, through the Middle East and finally to South East Asia and it provides communication to 33 countries. It's 24,200 miles (39,000 km) long.

In German, the word for when cables under the desk tangle and create a mess is "Kabelsalat"—"cable salad."

The O2 Arena in Greenwich is supported by 43 miles of high-strength cable which holds up 100,000 square meters of fabric.
