TAT-1 was the first submarine transatlantic telephone cable system. It was laid between Oban, Scotland and Clarenville, Newfoundland. Two cables were laid between 1955 and 1956 with one cable for each direction. It was inaugurated on September 25, 1956. The cable was able to carry 35 simultaneous telephone calls. A 36th channel was used to carry up to 22 telegraph lines.
TAT-3 was the third transatlantic telephone cable, in operation from 1963 to 1986. It had 414 kHz of bandwidth, allowing it to carry 138 telephone circuits. It was 3,518 nautical miles long, connecting Widemouth Bay in Cornwall, England to Tuckerton, New Jersey in the United States. It was owned by AT&T and GPO
TAT-4 was the fourth transatlantic telephone cable, in operation from 1965 to 1987. It operated at 384 kHz, initially carrying 128 telephone circuits between Saint-Hilaire-de-Riez, (France) and Tuckerton, New Jersey. It was co-owned by AT&T and France Telecom.
TAT-5 was AT&T Corporation's 5th transatlantic telephone cable, in operation from 1970 to 1993, carrying 720 3kHz channels, between Rhode Island, United States and Conil de la Frontera, (Cádiz), Spain. It had 361 repeaters.
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).
TAT-7 was the seventh transatlantic telephone cable, in operation from 1983 to 1994, initially carrying 4,000 3 kHz telephone circuits between New Jersey, Unites States and Porthcurno in southwest England. It was owned by AT&T, British Telecom and France Telecom.
TAT-8 was the 8th transatlantic communications cable and first transatlantic fiber-optic cable, carrying 280Mbits between the United States, Great Britain 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. 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.
TAT-9 was the 9th transatlantic telephone cable system, in operation from 1992 to 2004, operating at 560Mbits/sec between Europe and North America. It was built by an international consortium of co-owners and suppliers. Co-owners included AT&T Corporation, British Telecom and France Telecom.
TAT-10 was AT&T Corporation's 10th transatlantic telephone cable, in operation from 1992 to 2003, initially carrying 2 x 565 Mbit/s between United States and Norden in Germany.
TAT-11 was AT&T Corporation's 11th transatlantic telephone cable, in operation from 1993, initially carrying 2 x 565 Mbit/s between the United States and France.
TAT-12/13 is a ring cable system consisting of the 12th and 13th consortia transatlantic telephone cables, in operation from 1996, initially carrying 2 × 5 Gbit/s.
CANTAT-2 was the second Canadian transatlantic telephone cable, in operation from 1974 to 1992. It could carry 1,840 simultaneous telephone calls between Beaver Harbour, Nova Scotia and England.
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 century, all used optical fiber, and most now use optical amplifiers.
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 fiber technology to carry digital data, which includes telephone, Internet and private data traffic.
A transatlantic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first was laid across the floor of the Atlantic from Telegraph Field, Foilhommerum Bay, Valentia Island in western Ireland to Heart's Content in eastern Newfoundland. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days – the time it took to deliver a message by ship – to a matter of minutes. Transatlantic telegraph cables have been replaced by transatlantic telecommunications cables.
Transatlantic crossings are passages of passengers and cargo across the Atlantic Ocean between Europe or Africa and the Americas. The majority of passenger traffic is across the North Atlantic between Western Europe and North America. Centuries after the dwindling of sporadic Viking trade with Markland, a regular and lasting transatlantic trade route was established in 1566 with the Spanish West Indies fleets, following the Voyages of Christopher Columbus.
A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electric power transmission, 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.
The history of telecommunication began with the use of smoke signals and drums in Africa, the Americas and parts of Asia. In the 1790s, the first fixed semaphore systems emerged in Europe; however it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the larger history of communication.
The French Cable Hut is a historic building in Cape Cod National Seashore, near the Nauset Beach Light in Eastham, Massachusetts. Built in 1891, the hut formed a linkage point in the transatlantic telegraph cable of the French Cable Company connecting the cable, where it came ashore near the present site to its main station in Orleans. After the cable was abandoned in 1932, the hut was adapted for residential use. It has since been restored to its turn-of-the-century appearance by the National Park Service. The building was listed on the National Register of Historic Places in 1976.
