TAT-6 was the sixth transatlantic telephone cable. It was in operation from 1976 to 1994, with a bandwidth of 12MHz between Green Hill and Saint-Hilaire-de-Riez, Vendée, (France).
CANTAT-1 was the first Canadian transatlantic telephone cable, between Hampden, Newfoundland and eventually Grosses-Roches, Quebec and Oban, United Kingdom, which followed on from the success of TAT-1. It was conceived and approved as stage one of a proposed commonwealth round the world cable and was done at a cost of $8,500,000. The system was jointly owned by Cable & Wireless and the Canadian Overseas Telecommunication Corporation (COTC).
A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other. In the 19th and early 20th centuries, each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the 20th century, all cables installed used optical fiber as well as optical amplifiers, because distances range thousands of kilometers.
A 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. 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. Modern cables use optical fibre technology to carry digital data, which includes telephone, Internet and private data traffic.
Commercial Pacific Cable Company was founded in 1901, and ceased operations in October 1951. It provided the first direct telegraph route from America to the Philippines, China, and Japan.
SAT-3/WASC or South Atlantic 3/West Africa Submarine Cable is a submarine communications cable linking Portugal and Spain to South Africa, with connections to several West African countries along the route. It forms part of the SAT-3/WASC/SAFE cable system, where the SAFE cable links South Africa to Asia. The SAT-3/WASC/SAFE system provides a path between Asia and Europe for telecommunications traffic that is an alternative to the cable routes that pass through the Middle East, such as SEA-ME-WE 3 and FLAG. SAT-3 has a capacity of 340 Gbit/s while SAFE has a capacity of 440 Gbit/s. The SAT-3 system together with SAFE was built by a consortium of operators. As of 2006, major investors included Telkom Group, France Telecom (12.08%), Nitel (8.39%); TCI, a subsidiary of AT&T Inc. (12.42%); and VSNL (8.93%).
A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves for guiding cable over bow or stern or both. Bow sheaves, some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, as seen in the photo of CS Cable Innovator at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS Long Lines.
Global Marine Group is a British-headquartered specialist provider of installation, maintenance and repairs of submarine communications cable for the telecommunications, oil & gas and deep sea research industries.
The second CS Faraday was a cable ship built by Palmers Shipbuilding and Iron Company, Hebburn-on-Tyne, in 1922–23, as a replacement for the ageing CS Faraday built in 1874. Design of the new ship was influenced by long experience with the original ship.
USS Kailua (IX-71) was originally CS Dickenson, a civilian supply and personnel transport cable-repair ship of the Commercial Pacific Cable Company that was based in Honolulu serving the island cable stations at Midway and Fanning Island.
The MV Peter Faber is a French cable-laying vessel. In the Fall of 2008 the Peter Faber will be laying a telecommunication cable connecting Newfoundland, Greenland and Iceland. The Peter Faber made a relatively uncommon transit through the Northwest Passage to travel from its previous assignment in the Pacific Ocean.
The West Africa Cable System (WACS) is a submarine communications cable linking South Africa with the United Kingdom along the west coast of Africa that was constructed by Alcatel-Lucent. The cable consists of four fibre pairs and is 14,530 km in length, linking from Yzerfontein in the Western Cape of South Africa to London in the United Kingdom. It has 14 landing points, 12 along the western coast of Africa and 2 in Europe completed on land by a cable termination station in London. The total cost for the cable system is $650 million. WACS was originally known as the Africa West Coast Cable (AWCC) and was planned to branch to South America but this was dropped and the system eventually became the West African Cable System.
Africa Coast to Europe (ACE) is an optical-fiber submarine cable system serving 24 countries on the Europe, west coast and south Africa, managed by a consortium of 19 members.
C.S. Sovereign is a class DP2 type cable ship used for subsea cable installation and repair works. The ship was designed by BT Marine with Hart Fenton & Company as Naval Architects and built by Van der Giessen de Noord in 1991.
The Mafuta is a diamond-mining ship owned and operated by De Beers in the western coast of South Africa. Built in 1983 as Dock Express 20 for Dock Express Shipping, the semisubmersible, multirole, heavy-lift vessel was converted to the world's largest cable layer in 1993. In 2005, she was purchased by De Beers, and converted to a subsea diamond-mining ship by A&P Tyne over the course of 11 months. The ship's new name, Peace in Africa, may have implied that it was providing an alternative to blood diamonds. In 2013, still under ownership of De Beers Marine Namibia, the vessel was renamed to MV Mafuta.
The Eastern Mediterranean Optical System (EMOS-1) is a fiber optic cable linking Palermo, Italy with Lechaina, Greece; Marmaris, Turkey and Tel Aviv, Israel, which was created in Turkey in 1991. Consisting of three pairs which are split en route through branching units. The ship CS Vercors laid the cable. Each pair of fibres are capable of transmitting 1920 telephone calls in each direction.
Orange Marine is a wholly owned subsidiary of Orange S.A. It is a major actor in the laying of new submarine communications cables and the maintenance of existing cables across the world's oceans. The company is active in all areas of these activities, including the study (survey) and the shore ends. Orange Marine took control of Elettra on October 1, 2010, and now operates six cable ships - i.e. 15% of the world fleet. The CEO of Orange Marine and Elettra is Raynald Leconte, Chief Engineer of Mines.
The South Atlantic Cable System or SACS, is a submarine communications cable in the South Atlantic Ocean linking Luanda, Angola with Fortaleza, Brazil with a leg connecting the Brazilian archipelago of Fernando de Noronha as well. It is the first low latency routing between Africa and South America.
HMTS Monarch, launched on 8 August 1945 and completed during February 1946, was the fourth cable ship with that name. The ship was built for the General Post Office (GPO) for the laying and repair of submarine communications cable and was the largest cable ship in the world when completed and the first cable ship to have all electric cable machinery.
