TAT-13
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. This was the first TAT cable to use a ring structure, involving two stretches of cable across the ocean floor, which explains why two numbers (12 and 13) were used. All later cables also use a ring structure, but only use one number ( TAT-14 etc.). The cable connected between Long Island (at Shirley, New York), USA; Green Hill, Rhode Island, USA; Porthcurno, UK; Bude, UK; and Penmarch Penmarch (, ) is a commune in the Finistère department of Brittany, northwestern France. The cable was constructed for US$740 million and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transatlantic Telephone Cable
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. History When the first transatlantic telegraph cable was laid in 1858 by Cyrus West Field, it operated for only three weeks; subsequent attempts in 1865 and 1866 were more successful. In July 1866 '' Great Eastern'' sailed out of Valentia Island, Ireland and on July 26th landed at Hearts Content in Newfoundland. It was active until 1965. Although a telephone cable was discussed starting in the 1920s, to be practical it needed a number of technological advances which did not arrive until the 1940s. Starting in 1927, transatlantic telephone service was radio-based. TAT-1 (Tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erbium-doped Fiber Amplifier
An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. They are used as optical repeaters in the long distance fiberoptic cables which carry much of the world's telecommunication links. There are several different physical mechanisms that can be used to amplify a light signal, which correspond to the major types of optical amplifiers. In doped fiber amplifiers and bulk lasers, stimulated emission in the amplifier's gain medium causes amplification of incoming light. In semiconductor optical amplifiers (SOAs), electron-hole recombination occurs. In Raman amplifiers, Raman scattering of incoming light with phonons in the lattice of the gain medium produces photons coherent with the incoming ...

United Kingdom–United States Relations
Relations between the United Kingdom and the United States have ranged from close allies to military opponents since the latter declared independence from the former in the late 18th century. The Thirteen British Colonies that seceded from the Kingdom of Great Britain in 1776 fought a subsequent revolutionary war and a theatre of the Napoleonic Wars in 1812. During the World Wars the United States had surpassed the United Kingdom as the world's leading power, having overshadowed it economically from the late 19th century. Since 1940 the countries have been close military allies enjoying the Special Relationship built as wartime allies and NATO partners. They are bound together by shared history, an overlap in religion, common language, legal system and kinship ties that reach back hundreds of years, including kindred, ancestral lines among English Americans, Scottish Americans, Welsh Americans, Cornish Americans, Scotch-Irish Americans, Irish Americans, and American Britons.

France–United States Relations
France was the first ally of the new United States in 1778. The 1778 Treaty of Alliance between the two countries and the subsequent aid provided from France proved decisive in the American victory over Britain in the American Revolutionary War. France, however, was left heavily indebted after the war, which contributed to France's own revolution and eventual transition to a republic. The France-United States alliance has remained peaceful since, with the exceptions of the Quasi War from 1798 to 1799 and American combat against Vichy France (while supporting Free France) from 1942 to 1944 during World War II. Tensions, however, rose during the American Civil War, as France intervened militarily in Mexico and entertained the possibility of recognizing the separatist Confederate States of America, the defeat of which was followed by the United States sending a large army to the Mexican border and forcing the withdraw of French forces from Mexico. In the 21st century, difference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
France–United Kingdom Relations
The historical ties between France and the United Kingdom, and the countries preceding them, are long and complex, including conquest, Anglo-French Wars, wars, and Anglo-French alliance (other), alliances at various points in history. The Roman Empire, Roman era saw both areas largely conquered by Rome, whose fortifications largely remain in both countries to this day. The Norman conquest of England in 1066 decisively shaped English history, as well as the English language; English’s vocabulary is 45% derived from French, with the vast majority of large and complex words being of French origin and very similar in writing, but different in pronunciation and sometimes with a slightly different meaning. Throughout the Middle Ages and into the Early Modern Period, Kingdom of France, France and Kingdom of England, England were often bitter rivals, with both nations' monarchs English claims to the French throne, claiming control over France and France Auld Alliance, routine ...

Infrastructure Completed In 1996
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international community has created policy focused on sustain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcatel-Lucent
Alcatel–Lucent S.A. () was a French–American global telecommunications equipment company, headquartered in Boulogne-Billancourt, France. It was formed in 2006 by the merger of France-based Alcatel and U.S.-based Lucent, the latter being a successor of AT&T's Western Electric and Bell Labs. In 2014, the Alcatel-Lucent group split into two: Alcatel-Lucent Enterprise, providing enterprise communication services, and Alcatel-Lucent, selling to communications operators.

TAT-14
TAT-14 was the 14th consortium transatlantic telecommunications cable system. In operation from 2001 to 2020, it used wavelength division multiplexing. The cable system was built from multiple pairs of fibres—one fibre in each pair was used for data carried in one direction and the other in the opposite direction. Although optical fibre can be used in both directions simultaneously, for reliability it is better not to require splitting equipment at the end of the individual fibre to separate transmit and receive signals—hence a fibre pair is used. TAT-14 used four pairs of fibres—two pairs as active and two as backup. Each fibre in each pair carried 16 wavelengths in one direction, and each wavelength carried up to an STM-256 (38,486,016 kbit/s as payload). The fibres were bundled into submarine cables connecting the United States and the European Union (United Kingdom, France, the Netherlands, Germany, and Denmark) in a ring topology. By the time this cable went into o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
