Main One (cable System)
The Main One Cable is a submarine communications cable stretching from Portugal to South Africa with landings along the route in various west African countries. On April 28, 2008, it was announced that Main Street Technologies has awarded a turnkey supply contract for the Main One Cable System to Tyco Telecommunications. The cable system spans 14,000 km and provides additional capacity for international and Internet connectivity to countries between Portugal and South Africa on the west coast of Africa. The submarine cable project was designed in two phases, both of which were scheduled for completion in May 2010. The dual fiber pair, 1.28-Tbit/s, DWDM project connects Nigeria, Ghana, and Portugal in Phase 1 with onward connectivity through Portugal to Europe, Asia and the Americas. The Phase 1 cable system spans 6,900 kilometres. Additional connectivity extending to Angola and South Africa occurred in the second phase of the project. Main One provides international capacit ...

SAT-3/WASC (cable System)
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 ...

WACS (cable System)
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 (including Cape Verde and Canary Islands) and 2 in Europe (Portugal and England) 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. Landing points The cable has landed in the following countries and locations: #South Africa, Western Cape, Yzerfontein #Namibia, Swakopmund #Angola, Sangano near Luanda #Democratic Repub ...

ACE (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 20 members. The ACE cable connects more than 450 million people, either directly for coastal countries or through land links for landlocked countries such as Mali and Niger. ACE is also the first international submarine cable to land in Equatorial Guinea, Gambia, Guinea, Liberia, Mauritania, São Tomé and Príncipe and Sierra Leone. Agreements are being put in place to allow the arrival of other operators in countries along the ACE cable route. Guinea-Bissau is the next country to be connected to the submarine cable. ACE Consortium consists of telecommunications operators and member countries that have invested in the total 700 million dollars project, sometimes with the financial support of the World Bank. The consortium agreement was signed on 5 ... [...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 ...

Apollo (cable System)
Apollo is an optical submarine communications cable system crossing the Atlantic Ocean, owned by Apollo Submarine Cable System Ltd (a joint venture between Cable & Wireless Worldwide and Alcatel). It consists of 2 segments North and South, creating two fully diverse transatlantic paths. In early 2006, Level 3 Communications announced its purchase of 300 Gbit/s of capacity between Apollo North and Apollo South with an option to purchase up 300 Gbit/s of future capacity. This acquisition gives Level 3 a transatlantic path that does not pass through either London or New York City, which is desirable to carriers due to network diversity concerns. This purchase represents the single largest transaction of sub-sea capacity in history without laying new cable. Principal access points Apollo has principal access points at the following locations: ;United States * 111 8th Avenue * 60 Hudson Street * 165 Halsey Street * 2100 M Street, Washington DC * Equinix, Ashburn * US cable stations ...

Submarine Communications Cables In The South Atlantic Ocean
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of spe ...

Telecommunications Infrastructure
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumbea ...
