San Andres is the capital of the Colombian department of San Andrés and Providencia, an archipelago situated in the Caribbean Sea approximately 775 kilometres northwest of mainland Colombia. As an island territory geographically separated from the Colombian mainland, submarine cable connectivity is the primary means by which the island maintains fixed telecommunications links. One submarine cable lands at San Andres, providing a direct undersea connection within the Colombian national network.
The single cable serving San Andres is the San Andres Isla Tolu Submarine Cable (SAIT), which links the island to the Colombian mainland. This connection represents an intra-national corridor rather than an intercontinental or international route, serving to integrate a remote island community into Colombia's broader telecommunications infrastructure.
The San Andres Isla Tolu Submarine Cable (SAIT) is the sole submarine cable landing at San Andres. With a total length of 826 km, the cable reached ready-for-service status in 2010 and remains in draft status. Its route connects San Andres to Tolu, a coastal landing point on the Caribbean shore of mainland Colombia. As an entirely domestic cable, SAIT links two Colombian landing points, providing the island of San Andres with a dedicated undersea pathway to the Colombian mainland network.
Within Colombia's submarine cable infrastructure — which spans 12 cables across 10 landing points — San Andres ranks alongside Buenaventura, Parque Isla de Salamanca, and Puerto Colombia as single-cable landing points. The larger hubs of Cartagena and Barranquilla, with six and five cables respectively, anchor Colombia's international submarine cable connectivity, while San Andres and Tolu are connected to each other through the SAIT system, forming a dedicated domestic island corridor.
San Andres functions as a single-cable terminus within Colombia's submarine cable network. Its sole connection, the SAIT cable, runs exclusively between the island and the mainland port of Tolu, making it a point-to-point domestic link rather than a multi-cable hub with diverse international routing options. The cable's 826 km length reflects the considerable distance between San Andres and the Colombian mainland coast, a geographic reality that makes the undersea route the most direct means of connecting the archipelago.
In the broader Colombian submarine cable graph, San Andres represents a domestic endpoint whose connectivity depends entirely on the SAIT system. Its position as a geographically isolated island landing point with a single domestic cable underlines the distinct role that island territories play in shaping the structure and reach of a country's submarine cable network.
