Submarine Communications Cable
A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables were laid beginning in the 1850s and 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. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Territory, Australia, in 1871 in anticipation of the completion of the Australian Overland Telegraph Line in 1872 connecting to Adelaide, South Australia and thence to the rest of Australia. Subsequent generations of cables carried telephone traffic, then data transmission, data communications traffic. These early cables used copper wires in their cores, but modern cables use optical fiber technology to carry digital data, whic ...

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 June 2010 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portugal–Spain Relations
Portuguese-Spanish relations are closely aligned with one another, underpinned by shared membership of the Ibero-American Summit, Council of Europe, European Union, Eurozone, Schengen Area and NATO, and make up the vast majority of the Iberian Peninsula and Macaronesia. History Reconquista After the Umayyad conquest of Hispania, Umayyad conquest of the Iberian Peninsula, a long process of reconquest (in Portuguese language, Portuguese and Spanish language, 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 Portugal, County of Portucale, successively a vassal of the kingdoms of Asturias, Kingdom of Galicia, Galicia, Kingdom of León, León, eventually rebelled and won Battle of São Mamede on 24 June 1128, led by Afonso Henriques, who, after defeating the Moors in the Battle of Ourique, proc ...

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 Internet Service Providers, ISP subscriptions, overall number of host (network), hosts, Internet Exchange Point, IXP-traffic, and overall available bandwidth (computing), 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, and Egypt, as well as smaller economies like Mauritius and the Seychelles. In general, only 43% of the African population has access to the Internet as of 2021. 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 serious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Communications Cables In The South Atlantic Ocean
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Equiano (submarine Communications Cable)
Equiano is a private transatlantic communications cable that connects western Europe (Portugal) with southern Africa ( Melkbosstrand, South Africa). Branching points along the way connect to Togo, Nigeria, the island of St. Helena and Namibia. The cable was announced by Google in June 2019 and was originally due to go live in 2021. After delays due to COVID-19 and other issues, Equiano was eventually launched by Google in September 2022, having reached its final destination of South Africa. SEACOM began services on the cable in March 2023. History In June 2019, Google announced that it would be investing in another private international subsea cable — Equiano — its third private subsea cable after Curie (completed in 2019), and Dunant (completed in 2020). The Equiano cable, which will link Europe with western and southern Africa was named for Olaudah Equiano, a Nigerian-born writer and abolitionist. The cable was built and laid by Alcatel-Lucent Submarine Networks (ASN). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. History On 6 August 2023, the cable system snapped simultaneously with the SAT-3 Cable System after a rock fall in the Congo Canyon. Internet Speeds in Sub-Saharan Africa were impact ...

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 . History SAT-3/WASC/SAFE began operations in 2001, providing the first links to Europe for West African internet users and, for South Africans, taking up service from SAT-2 which was reaching maximum capacity. SAT-2 had been brought into service in the early 1990s as a replacement for the original undersea cable SAT-1 whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
