{{Short description|Transatlantic telephone cable}}
'''TAT-6''' was the sixth [[transatlantic telephone cable]]. It was in operation from 1976 to 1994, with a bandwidth of 12MHz (4,000 telephone circuits) between [[South Kingstown, Rhode Island|Green Hill]] ([[United States]]) and [[Saint-Hilaire-de-Riez]], [[Vendée]], ([[France]]).<ref>{{cite book |title=1990 World's Submarine Telephone Cable Systems |publisher=U.S. Department of Commerce |year=1990}}</ref><ref>{{Cite web|url=http://atlantic-cable.com//Cables/CableTimeLine/index1951.htm|title=History of the Atlantic Cable & Submarine Telegraphy - Cable Timeline|website=atlantic-cable.com|access-date=2018-08-05}}</ref>

Known as the SG coaxial cable system, designed by [[Bell Labs]], the cable is {{Convert|3396|nmi|km|-2}} with repeater spacing of {{Convert|5.1|nmi|km|0}}.
The deep sea portion, some {{Convert|3000|nmi|km|-2}} in length, was laid by the Cable Ship ''Long Lines'', owned by AT&T. Portions of the shore sections were laid by the French Cable Ship ''Vercors''.

The SG Undersea Cable System was designed by Bell Laboratories at their Allentown, PA, Greensboro, NC, Holmdel, NJ, and Whippany, NJ facilities.<ref>The Bell System Technical Journal, Volume 57, Number 7, Part 1, September 1978</ref>

A few years later, [[TAT-7]] was put into service between [[Tuckerton, New Jersey]], and Lands End, England, and was the last analog Transatlantic undersea system.

The following system, [[TAT-8]], was implemented by [[AT&T Corp.]] (with [[Bell Laboratories]]), [[Standard Telephones and Cables|STC]] (with [[BT Group|British Telecom]]), and [[Alcatel]] (with France Telecom). This was the first Transatlantic fiber-optic system, had greatly increased capacity and performance.
