About DBpedia

TAT-8是第八条和第一条跨大西洋光纤光缆,连接美国,英国和法国,其传输速率为280Mbit/s(支持最多40,000个电话电路)。 它由AT&T公司,法国电信和英国电信领导的公司联盟于1988年建造。AT&T贝尔实验室开发了电缆中所使用的技术。通过使用位于英国海岸外大陆架水下的一个创新性拆分装置,它仅跨大西洋一次就连接了这三个国家。电缆在分别在美国新泽西州的,英国的和法国的登陆。 该系统于1988年以3.35亿美元的初始成本建造 ,并于2002年停止使用。

dbo:abstract TAT-8 fue el octavo telefónico, inicialmente con una capacidad de 40 000 circuitos telefónicos (llamadas simultáneas), entre Estados Unidos, Inglaterra y Francia. Fue construido en 1988 por un consorcio de compañías de telecomunicaciones formado por AT&T, France Télécom y British Telecom entre otros. El TAT-8 era capaz de ofrecer servicio a tres países con un solo cable transatlántico submarino, que costó 335 millones de dólares. El sistema contenía tres cables de fibra óptica, dos en activo, más uno de seguridad, que eran capaces de transmitir datos a una velocidad de 20 Mbps. Finalmente, el TAT-8 se retiró del servicio en el año 2002. (es) TAT-8 was the 8th transatlantic communications cable and first transatlantic fiber-optic cable, carrying 280 Mbit/s (40,000 telephone circuits) between the United States, United Kingdom and France. It was constructed in 1988 by a consortium of companies led by AT&T Corporation, France Télécom, and British Telecom. AT&T Bell Laboratories developed the technologies used in the cable. The system was made possible by optical amplifiers acting as repeaters with advantages over the electrical repeaters of former cables. They were less costly and could be at greater spacing with less need for associated hardware and software. It was able to serve the three countries with a single transatlantic crossing with the use of an innovative branching unit located underwater on the continental shelf off the coast of Great Britain. The cable lands in Tuckerton, New Jersey, USA, Widemouth Bay, England, UK, and Penmarch, France. The system was built at an initial cost of US$335 million in 1988 and was retired from service in 2002. Capacity was reached in eighteen months despite optimistic predictions that the capacity would not be filled for a decade and some that it would never be filled and no other cables would be needed. (en) TAT-8 — трансатлантический телефонный кабель 8-го поколения, содержащий 40 000 телефонных цепей (одновременных звонков) между США, Францией и Великобританией. Линия была спроектирована в 1988 году консорциумом компаний во главе с AT&T, France Telecom и British Telecom. Система проработала с 1988 по 2002 год, стоимость проекта оценивается в 335 миллионов долларов. Это первая трансатлантическая кабельная система, в который использовалась волоконно-оптическая линия, совершившая революцию в телекоммуникации. Система включала два рабочих волокна и одно резервное. Сигнал на каждом из оптических волокон модулировал 295,6 Мбит/с (20 Мбит/с трафика), и полностью восстанавливался в ретрансляторах, размещённых на расстоянии около 40 км друг от друга. В первые два года наблюдались проблемы, связанные с эксплуатацией. Причиной служили рыбы (акулы), которые повреждали линию передачи и тем самым периодически лишали связи. Эта проблема появилась из-за того что была убрана защита от электрических помех, в которой не нуждаются волоконно-оптические линии. Следующий трансатлантический кабель уже имел защиту против акул.
