Sardina, Canary Islands, Spain: Submarine Cable Landing Point

Sardina is a coastal landing point located in the Canary Islands, the Spanish archipelago situated in the Atlantic Ocean off the northwest coast of Africa. As an island territory, the Canary Islands depend on submarine cable connections to maintain telecommunications links both within the archipelago and beyond. Sardina hosts one submarine cable, the Tenerife-Gran Canaria cable, which connects two of the major islands within the Canary Islands group.

The single cable landing at Sardina operates entirely within Spain, linking islands of the Canary archipelago rather than spanning intercontinental distances. This positions Sardina as a point of intra-archipelago connectivity, serving the shorter-range but essential inter-island corridor between Tenerife and Gran Canaria.

Cables Landing at Sardina, Canary Islands, Spain

Tenerife-Gran Canaria is a submarine cable measuring 110 km in length that reached ready-for-service status in 1999. The cable connects landing points within Spain, linking the islands of Tenerife and Gran Canaria, two of the principal islands of the Canary Islands. Both endpoints of this cable fall within Spanish territory, making it a wholly domestic inter-island connection within the archipelago.

Regional Context

Within Spain's broader submarine cable network, Sardina is one of 46 landing points across the country, which together host 34 submarine cables in total. Spain's other landing points include more heavily connected locations such as Alta Vista in the Canary Islands, Barcelona, Bilbao, Granadilla de Abona, Santa Cruz de La Palma, and Valencia, each of which hosts three cables. Sardina, with one cable, ranks in the upper 56 percent of Spanish landing points by cable count, reflecting the large number of smaller or more specialised landing points distributed across the country's coastline and island territories.

Network Role

Sardina functions as a single-cable terminus rather than a multi-cable hub, anchoring one end of the Tenerife-Gran Canaria inter-island link. This cable enables direct submarine connectivity between two of the Canary Islands' most significant islands, supplementing whatever overland or aerial infrastructure the archipelago relies upon for inter-island telecommunications. Within the Canary Islands specifically, Sardina joins other island landing points such as Alta Vista, Granadilla de Abona, and Santa Cruz de La Palma in forming the submarine cable geography of the archipelago.

In the broader Spanish submarine cable graph, Sardina represents one of the more specialised landing points: a short-range, single-cable, wholly domestic terminus dedicated to inter-island connectivity. Its presence illustrates how submarine cable infrastructure within Spain extends beyond intercontinental routes to serve the internal connectivity needs of geographically dispersed island territories.
