West Africa Submarine Cable
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 (about 13%), France Telecom (12.08%), Nitel (8.39%); TCI, a subsidiary of AT&T Inc. (12.42%); and VSNL (8.93%). Bandwidth costs Prices for SAT-3 bandwidth in the African countries it serves are high (US$4,500–12,000 per Mbit/s per month, over 50 times greater than bandwidth ...

Submarine Communications Cable
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. Modern cables are typically about in diameter and weigh around for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Terr ...

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cable Landing Point
A cable landing point is the location where a submarine or other underwater cable makes landfall. The term is most often used for the landfall points of submarine telecommunications cables and submarine power cables. The landing will either be direct (in the case of a point-to-point cable system) or via a branch from a main cable using a submarine branching unit. The branch can be several kilometres long. Selection criteria Cable landing points are usually carefully chosen to be in areas: # that have little marine traffic to minimise the risk of cables being damaged by ship anchors and trawler operations; # with gently sloping, sandy or silty sea-floors so that the cable can be buried to minimise the chance of damage; # without strong currents that would uncover buried cables and potentially move cables. Such locations are rare, and will usually be the shared landfall point for several cable systems. Associated facilities Frequently, there will be a nearby cable landing ...
