Sangano, Angola: Submarine Cable Landing Point

Sangano is a submarine cable landing point located on the Atlantic coast of Angola. Two submarine cables make landfall here, making Sangano the most connected landing point in Angola by cable count. The cables landing at Sangano serve distinct corridors: one running northward and southward along the West African coastline, and one crossing the South Atlantic to Brazil.

The combination of a regional African cable and a transatlantic cable positions Sangano as a point where intra-African and intercontinental connectivity converge. The West Africa Cable System (WACS) links Angola to a chain of West and Central African nations, while the South Atlantic Cable System (SACS) provides a direct connection between Angola and South America. Together, these two systems make Sangano a landing point that bridges multiple submarine cable corridors simultaneously.

Cables Landing at Sangano

The West Africa Cable System (WACS) is a 14,530 km submarine cable that reached ready-for-service status in 2012. In addition to Angola, WACS connects Cameroon, Cape Verde, Côte d'Ivoire, the Democratic Republic of the Congo, Ghana, and Namibia. The system runs along the western coast of Africa, linking a broad set of Central and West African nations and extending northward toward the broader intercontinental network.

The South Atlantic Cable System (SACS) is a 6,165 km submarine cable that became ready for service in 2018. SACS connects Angola directly to Brazil, forming a transatlantic link across the South Atlantic Ocean. This cable represents one of the few direct connections between the African continent and South America, and Sangano serves as the African terminus of that route.

Regional Context

Angola's submarine cable infrastructure spans seven landing points, with Sangano hosting more cables than any other individual landing point in the country. The remaining six Angolan landing points - Cabinda, Cacongo, Cacuaco, Luanda, N'zeto, and Soyo - each host a single submarine cable. Sangano's two-cable presence distinguishes it within Angola's national submarine cable geography.

Network Role

Sangano functions as a multi-cable hub within Angola, hosting both a regional West African cable and a transatlantic cable. WACS extends Angola's connectivity across a wide arc of the African Atlantic coast, reaching Cameroon, Cape Verde, Côte d'Ivoire, the Democratic Republic of the Congo, Ghana, and Namibia. SACS simultaneously provides Angola with a direct submarine route to Brazil, a connection that is geographically rare given the breadth of the South Atlantic.

The presence of two cables - one regional and one intercontinental - gives Sangano a distinctive role in Angola's submarine cable network. While each of the country's other six landing points terminates a single cable, Sangano stands apart as the only Angolan landing point connecting both to neighboring African nations and directly across to another continent. Within the regional submarine cable graph, this dual-corridor position makes Sangano the most connected landing point in Angola.
