Ustica, Italy

Ustica, Italy: Submarine Cable Landing Point

Ustica is a small Italian island situated in the Tyrrhenian Sea, approximately 52 kilometres north of Capo Gallo, Sicily. With a resident population of roughly 1,300 people, it is one of Italy's minor islands, yet it participates in the country's submarine cable network as a landing point for domestic connectivity infrastructure. One submarine cable currently lands at Ustica, linking the island to other points within Italy and providing it with the subsea connectivity that island communities depend upon.

The single cable serving Ustica is the Piano Isole Minori system, a domestic Italian cable that, as its name suggests, is designed to connect Italy's smaller islands to the mainland network. This places Ustica within an intra-national, inter-island connectivity corridor rather than an intercontinental or broad regional one.

Cables Landing at Ustica

Piano Isole Minori is a submarine cable system spanning 830 kilometres, with a Ready for Service (RFS) date of 2024, currently at draft status. The cable connects multiple landing points within Italy, serving the country's minor islands as part of a domestic network initiative. Ustica is one of the landing points on this system, which links Italian islands to one another and to the Italian mainland. No other countries are served by this cable.

Regional Context

Within Italy's submarine cable landscape, Ustica is a single-cable landing point, placing it at the more modest end of the national spectrum. Italy hosts several significantly larger cable hubs: Mazara del Vallo serves eight cables, Genoa serves six, and Catania serves three, while Bari, Civitavecchia, and Olbia each serve two. Ustica's role is accordingly focused and local, oriented toward island connectivity rather than international or intercontinental traffic.

Network Role

Ustica functions as a terminus on the Piano Isole Minori cable, a domestic system designed to extend subsea connectivity to Italy's smaller and more remote island communities. As a single-cable landing point on an intra-national system, Ustica does not serve as a hub for international data flows but instead benefits from a connectivity link that ties it into Italy's broader terrestrial and subsea network. The cable's 830-kilometre length reflects the distributed nature of the Italian minor islands it is intended to serve.

In the regional submarine cable graph, Ustica represents the category of island landing points whose primary function is domestic inclusion rather than international transit, ensuring that even small, remote communities in the Tyrrhenian Sea maintain a dedicated subsea connection to the national network.
