Cacongo, Angola: Submarine Cable Landing Point

Cacongo is a town in Cabinda Province, Angola, situated on Lândana Bay approximately one kilometre south of the mouth of the Chiloango River. The town, which is sometimes still referred to by its former name Lândana, serves as a submarine cable landing point hosting one submarine cable. Its coastal position on the Atlantic-facing shoreline of Cabinda Province makes it a natural terminus for marine cable infrastructure in this northern exclave of Angola.

The single cable landing at Cacongo is the Unitel North Submarine Cable (UNSC), a domestic system connecting multiple points along the Angolan coast. As an entirely intra-national cable, the UNSC enables connectivity along the Angolan coastal corridor rather than providing intercontinental links. Cacongo therefore functions as a domestic terminus within a regional submarine cable route serving Angola's coastal communities.

Cables Landing at Cacongo

The Unitel North Submarine Cable (UNSC) is the sole submarine cable landing at Cacongo. The system spans 1,145 kilometres and reached ready-for-service status in 2023 on a draft basis. All other landing points on the UNSC are also located within Angola, making this an entirely domestic submarine cable. The cable links Cacongo with other Angolan coastal communities along the Atlantic seaboard, providing an intra-national marine communications route along this stretch of the West African coast.

Regional Context

Angola's submarine cable infrastructure spans seven landing points across the country, with Cacongo hosting one of the five cables that land in Angola overall. Among its regional peers, Sangano leads with two cables, while Cabinda, Cacuaco, Luanda, N'zeto, and Soyo each host one cable — placing Cacongo alongside this latter group in terms of cable count. Cacongo's distinguishing characteristic within this national picture is its role as a landing point specifically for the UNSC, a domestic system oriented toward Angola's northern coastal provinces.

Network Role

Cacongo functions as a single-cable terminus within Angola's domestic submarine cable network. The UNSC, landing here as one of its Angolan endpoints, provides a submarine pathway along the national coastline rather than connecting Angola to foreign cable systems or international internet exchanges. This positions Cacongo as a contributor to intra-national coastal connectivity, linking the Cabinda Province enclave into a submarine network that runs along Angola's Atlantic shore.

Within the regional submarine cable graph, Cacongo's participation in the UNSC ensures that Cabinda Province's coastal communities are reached by marine cable infrastructure — a meaningful inclusion given that Angola's submarine cable development as a whole dates back only to 2002 and continues to expand across multiple landing points along this West African coastline.
