Porquerolles, France

Porquerolles: Submarine Cable Landing Point

Porquerolles is an island located in the Îles d'Hyères, in the Var department of the Provence-Alpes-Côte d'Azur region of France. As an inhabited island with a small permanent population, its connectivity to the French mainland depends on the kind of fixed infrastructure that submarine cables provide. One submarine cable lands at Porquerolles, linking the island within French territorial waters through a short intra-national connection.

The single cable serving Porquerolles is the Îles d'Hyères Cable, a relatively short system that connects points entirely within France. This makes Porquerolles a domestic landing point rather than a terminus on any intercontinental or inter-regional route. The cable's purpose is fundamentally local: providing a physical subsea link between the island and other points along the French coast.

Cables Landing at Porquerolles

The Îles d'Hyères Cable is the sole submarine cable landing at Porquerolles. The system spans 45 kilometres and reached ready-for-service status in 1996. Both endpoints of this cable are located in France, making it an entirely domestic connection. Its short length reflects the geographic reality of linking the Îles d'Hyères archipelago to the nearby French mainland coastline.

Regional Context

France hosts 34 submarine cables across 27 landing points, and Porquerolles, with a single cable, sits among the less densely connected of those locations. Within the national landscape, it ranks in the top 85 percent of French landing points by cable count. Nearby Marseille serves as the dominant hub in southern France with 16 cables, while other French Mediterranean and coastal sites such as Ajaccio and Bastia each host between one and two cables, placing Porquerolles in a comparable tier to those smaller island landing points.

Network Role

Porquerolles functions as a single-cable terminus serving a domestic intra-island corridor. The Îles d'Hyères Cable connects the island exclusively to other points in France, meaning Porquerolles plays no direct role in international submarine cable routing. The landing point's purpose is localised: sustaining a subsea link between a small island community and the French mainland.

Within the broader French submarine cable graph, Porquerolles represents a category of landing point defined by domestic necessity rather than international connectivity. Its presence in the national infrastructure illustrates how submarine cables serve not only transoceanic routes but also the more modest task of connecting small island populations to the mainland network.
