Porquerolles, France: Submarine Cable Landing Point

Porquerolles is an island in the Îles d'Hyères, located in the Var department of the Provence-Alpes-Côte d'Azur region of France. As an inhabited island separated from the French mainland, it relies on submarine cable infrastructure to maintain its connectivity. One submarine cable lands at Porquerolles, linking it to the broader French national network via an intra-country connection.

The single cable landing here, the Îles d'Hyères Cable, represents a domestic French corridor rather than an intercontinental or international link. Both endpoints of this cable reside within France, reflecting the island's geographic situation as part of an archipelago that requires dedicated undersea infrastructure to bridge the gap to the mainland or neighbouring islands.

Cables Landing at Porquerolles

The Îles d'Hyères Cable is the sole submarine cable landing at Porquerolles. With a length of 45 km, it was ready for service in 1996 and remains classified as a draft entry in submarine cable records. Both endpoints of the cable are located within France, making this an entirely domestic connection. Its relatively short length is consistent with its role of linking the Île de Porquerolles to the French mainland or other points along the nearby coast, rather than spanning international or intercontinental distances.

Regional Context

Within France's submarine cable landscape, which spans 34 cables across 27 landing points, Porquerolles hosts a single cable, placing it in the same tier as Bastia and Bonifacio, which each also serve one cable. By contrast, Marseille stands as France's dominant submarine cable hub with 16 cables, while Ajaccio, Cayeux-sur-Mer, and Lannion each host two cables. Porquerolles ranks within the top 85 percent of French landing points by cable count, reflecting the relatively modest but meaningful role that small island terminals play in the national submarine network.

Network Role

Porquerolles functions as a single-cable terminus, providing the Île de Porquerolles with its dedicated undersea link to the rest of France. The Îles d'Hyères Cable, at 45 km, serves a clearly defined intra-national corridor, addressing the practical requirement of connecting a small, permanently inhabited island to the mainland telecommunications network. There is no international routing capacity at this landing point; its scope is entirely domestic.

As a single-cable terminus on a small island, Porquerolles occupies a specialised position in the French submarine cable graph — one defined by local connectivity rather than broader international traffic routing. Its presence nonetheless illustrates that France's submarine cable infrastructure extends beyond major international hubs to serve even small island communities with dedicated undersea links.
