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.〔("''Same Day Analysis: WASACE Plans Submarine Cable Connecting Africa to Europe, Latin America and North America''" ) Global Insight, 28 November 2011〕 ==Landing points== The cable has landed in the following countries and locations: #South Africa, Western Cape, Yzerfontein #Namibia, Swakopmund #Angola, Sangano near Luanda #Democratic Republic of Congo, Muanda #Republic of Congo, Matombi near Pointe Noire #Cameroon, Limbe, near Douala #Nigeria, Lekki, near Lagos #Togo, Afidenyigba near Lomé #Ghana, Nungua near Accra #Ivory Coast, Abidjan #Cape Verde, Palmarejo near Praia #Canary Islands, Telde(el Goro) near Las Palmas #Portugal, Sesimbra near Seixal #United Kingdom, Brean near Highbridge (fiber link is extended by underground cable to London) The landings in Namibia, the DRC, the Republic of Congo and Togo will provide the first direct connections for these countries to the global submarine cable network. While all earlier submarine cables were terminated at South Africa's international submarine gateways in Melkbosstrand or Mtunzini the WACS cable has been landed at Yzerfontein in order to reduce risk of complete isolation from the rest of the world in the case of damages by earthquakes or a large ship dragging its anchor. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WACS (cable system)」の詳細全文を読む スポンサード リンク
