Candelaria, Canary Islands, Spain: Submarine Cable Landing Point

Candelaria is a municipality on the eastern coast of Tenerife, in the Canary Islands, an autonomous community of Spain situated in the Atlantic Ocean off the northwestern coast of Africa. As a submarine cable landing point, Candelaria hosts two cables that connect it within the broader Spanish and inter-island cable network. The two cables landing here — Pencan-8 and CANDALTA — both link Candelaria to other points within Spain, establishing this location as a node in the domestic and inter-island connectivity fabric rather than an intercontinental gateway.

The presence of two submarine cables places Candelaria among a recognized set of cable landing points in Spain, which collectively spans 34 submarine cables across 46 landing points. Both cables serving Candelaria are relatively short-distance systems, consistent with an inter-island or regional corridor role connecting the Canary Islands archipelago to the Spanish mainland or other island territories.

Cables Landing at Candelaria

Pencan-8 is a submarine cable system with a length of approximately 1,400 km, with a Ready for Service (RFS) date of 2011. This cable connects Candelaria to other landing points in Spain, making it a domestic Spanish cable system. Its length suggests it spans a meaningful distance, likely linking the Canary Islands to the Iberian Peninsula or to other points within the Spanish national network.

CANDALTA is a significantly shorter submarine cable, measuring 110 km in length, with an RFS date of 1999, making it the older of the two systems at this landing point. Like Pencan-8, CANDALTA connects to other locations within Spain. At 110 km, this cable is characteristic of a short inter-island link, providing connectivity within the Canary Islands themselves or to a nearby Spanish territory.

Regional Context

Within Spain's submarine cable landscape, Candelaria sits alongside other Canary Islands landing points such as Alta Vista, Granadilla de Abona, and Santa Cruz de La Palma, each of which hosts three cables. On the Spanish mainland, landing points including Barcelona, Bilbao, and Valencia also each host three cables. With two cables, Candelaria ranks in the upper 88% of Spain's 48 landing points by cable count, representing a modest but established presence in the national submarine cable map.

Network Role

Candelaria functions as a two-cable landing point within the Spanish domestic cable network, serving an inter-island or regional corridor rather than an intercontinental route. The combination of the shorter CANDALTA system, operational since 1999, and the longer Pencan-8 system, commissioned in 2011, gives Candelaria a degree of cable redundancy within its regional segment. Both systems terminate within Spain, meaning connectivity flows through this location are oriented toward domestic Spanish network endpoints.

As one of several Canary Islands landing points in Spain's 46-site cable infrastructure, Candelaria contributes to the distributed cable access across the archipelago. In the regional submarine cable graph, its role is that of a complementary landing point that reinforces inter-island and island-to-mainland connectivity alongside larger hubs in the same island group.
