Piedra Santa, Spain

Piedra Santa, Spain: Submarine Cable Landing Point

Piedra Santa is a submarine cable landing point located in Spain, forming part of the country's broader coastal cable infrastructure. Two submarine cables land at this location, both operating within Spanish territory. The cables connecting here — Subcan Link 1 and Subcan Link 2 — link points entirely within Spain, indicating that Piedra Santa serves a domestic or inter-island corridor rather than an intercontinental one.

With both cables relativley short in length and limited to Spanish endpoints, Piedra Santa functions as a regionally focused node. The "Subcan" naming convention shared by both cables suggests a connection associated with the Canary Islands, pointing to an intra-Spanish island connectivity role for this landing point.

Cables Landing at Piedra Santa, Spain

Subcan Link 1 is a submarine cable measuring 143 km in length, with a ready-for-service (RFS) date of 2002 and currently listed as draft status. Its endpoints are located entirely within Spain, making it a domestic submarine link.

Subcan Link 2 is a submarine cable measuring 136 km in length, also with an RFS date of 2002 and listed as draft status. Like Subcan Link 1, its endpoints are confined to Spain, further establishing Piedra Santa's role as a node within a domestic cable system. The two cables together represent a paired deployment, both commissioned in the same year and of comparable length.

Regional Context

Spain hosts 34 submarine cables across 46 landing points, and Piedra Santa, with its 2 cables, ranks within the top 88% of Spanish landing points by cable count. Several other Spanish landing points — including Barcelona, Bilbao, Valencia, Granadilla de Abona, Alta Vista in the Canary Islands, and Santa Cruz de La Palma in the Canary Islands — each host three cables, placing them a step above Piedra Santa in terms of cable count. Piedra Santa therefore represents a more focused, smaller-scale node within Spain's overall submarine cable network.

Network Role

Piedra Santa serves as a two-cable terminus within a domestic Spanish submarine cable corridor. Both Subcan Link 1 and Subcan Link 2 are short-range cables — 143 km and 136 km respectively — connecting points entirely within Spain. This positions Piedra Santa as a node supporting intra-national connectivity, most likely as part of the cable infrastructure linking mainland Spain or between Spanish island groups, given the shared "Subcan" designation of both cables.

Rather than functioning as a hub for international or intercontinental traffic, Piedra Santa's role is defined by the pairing of two domestic cables deployed simultaneously in 2002. Within the broader Spanish submarine cable graph, it represents a dedicated domestic link point, complementing the larger multi-cable landing points that handle both national and international traffic across Spain's extensive coastline.
