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 ...

Portugal–Spain Relations
Portugal–Spain relations describes relations between the governments of the Portuguese Republic and the Kingdom of Spain. The two states make up the vast majority of the Iberian Peninsula and as such, the relationship between the two is sometimes known as Iberian relations. In recent years, both countries have enjoyed a much friendlier relationship. Together, they are full-time members of the Ibero-American Summit, European Union, Eurozone, Schengen Area and NATO. Country comparison History Reconquista After the Umayyad conquest of the Iberian Peninsula, a long process of reconquest (in Portuguese and Spanish: Reconquista) began. The Battle of Covadonga and the establishment of the Kingdom of Asturias are often regarded as the starting points of this process. Several Christian kingdoms emerged in the peninsula thereafter. The County of Portucale, successively a vassal of the kingdoms of Asturias, Galicia, León, eventually rebelled and won Battle of São Mamede on ...

Portugal–South Africa Relations
Portugal – South Africa relations refer to the current and historical relationship between Portugal and South Africa. Nowadays the two countries have solid relations, with South Africa representing a major partner for Portugal amongst AU members. South Africa has an Embassy in Lisbon. It also has Honorary Consulates in Porto and Funchal, Madeira. Portugal has an Embassy in Pretoria. In addition, there are Consulates-General in Johannesburg and Cape Town, and Honorary Consulates in Durban, Port Elizabeth and Welkom. History Exploration Early explorers had set out with one purpose in mind, which was to discover a new sea route to the Orient. It is unlikely that they had any idea of achieving anything more than discovering and opening new channels of trade and commerce for Portugal. Furthermore, they were probably discouraged from any attempt to penetrate the interior of the country or to form settlements along the coast by the inhospitable terrain and by the hostile and w ...

Internet In Africa
The Internet in Africa is limited by a lower penetration rate when compared to the rest of the world. Measurable parameters such as the number of ISP subscriptions, overall number of hosts, IXP-traffic, and overall available bandwidth are indicators that Africa is far behind the "digital divide". Moreover, Africa itself exhibits an inner digital divide, with most Internet activity and infrastructure concentrated in South Africa, Morocco, Egypt as well as smaller economies like Mauritius and Seychelles. In general, only 24.4% of the African population have access to the Internet, as of 2018. Only 0.4% of the African population has a fixed-broadband subscription. The majority of internet users use it through mobile broadband. During the COVID-19 pandemic, many people who were not connected to the internet lost access to health care and education. Production in all industries was seriously harmed. While the telecommunications market in Africa is still in its early stages of dev ...

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 ...

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 ...

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 ...

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 ...
