Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
An example is the cable between Singapore and Indonesia, which was partly robbed in 2013: 31,7 km and 418 tons of cables were removed. [33] Another scenario is a criminal group threatening to harm cables if no ransom is received.

The presence of cables in the oceans can be a danger to marine life. With the proliferation of cable installations and the increasing demand for inter-connectivity that today's society demands, the environmental impact is increasing. Submarine cables can impact marine life in a number of ways.
Facebook's subsidiary – Edge USA – owns 80% of the cable and is the landing party for the US landing site at Lynn, contracting with the site's owner GTT. Vodafone is the landing party for the UK landing site at Bude through its subsidiary Apollo Submarine Cable System. [9] In September 2021, Orange announced it had landed the cable in Le Porge.
When the first transatlantic telegraph cable was laid in 1858 by Cyrus West Field, it operated for only three weeks; a subsequent attempt in 1866 was more successful. [citation needed] On July 13, 1866 the cable laying ship Great Eastern sailed out of Valentia Island, Ireland and on July 27 landed at Heart's Content in Newfoundland, completing the first lasting connection across the Atlantic.
