A telecom cable, or submarine communications cable, is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. Modern cables use optical fiber technology to carry digital data, which includes telephone, Internet and private data traffic.
Modern cables are typically about 1 inch (25 mm) in diameter and weigh around 2.5 tons per mile (1.4 tonnes per km) for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore.
Telecom Cables is a static data layer. They are point-by-point lines that you can draw in, edit or remove when making a plan.
Telecom Cables create the following pressures on the ecosystem:
Telecom Cables disallow the bottom trawl fishing fleet only. During construction the other two fishing fleets (Industrial and Pelagic Trawl Catch and Drift and Fixed Nets Catch) are also disallowed.
The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic.
