Olbia is a city on the northeastern coast of Sardinia, the autonomous island region of Italy, where it serves as co-capital of the Province of Gallura alongside Tempio Pausania. Its position on the Tyrrhenian Sea makes it a natural candidate for submarine cable infrastructure connecting Sardinia to the Italian mainland. Two submarine cables land at Olbia, both of which link to other points within Italy, establishing this landing point as a node in Italy's domestic inter-island and coastal cable network.
Both cables landing at Olbia operate within an intra-Italian corridor, reflecting Sardinia's reliance on submarine links to maintain connectivity with the peninsula and other Italian territories. The combination of the Unitirreno and Janna cables gives Olbia a domestic-focused cable presence, distinct from international gateway landing points elsewhere in Italy.
Unitirreno is a submarine cable measuring 1,156 km in length, with a ready-for-service date of 2025, currently at draft status. The cable connects landing points entirely within Italy, making it an intra-national system. As one of the longer domestic cables in Italy's submarine network, Unitirreno represents a significant addition to Olbia's connectivity profile upon its completion.
Janna is a submarine cable measuring 634 km in length, with a ready-for-service date of 2005. Like Unitirreno, it connects landing points within Italy, functioning as a domestic submarine link. Janna has provided Olbia with sub-sea connectivity for two decades and remains part of the active cable infrastructure at this landing point.
Within Italy's submarine cable landscape, Olbia ranks among the more modestly connected of the country's 55 landing points. Italy hosts 37 submarine cables across those landing points, with major hubs such as Mazara del Vallo (9 cables), Genoa (7 cables), and Catania (5 cables) serving considerably larger cable counts. Olbia's two cables place it alongside Civitavecchia and Lampedusa, which also host two cables each, reflecting a tier of landing points that serve more specialized or regional connectivity roles rather than broad international gateway functions.
Olbia functions as a two-cable landing point within Italy's intra-national submarine cable graph, with both the Unitirreno and Janna systems operating exclusively between Italian endpoints. This configuration positions Olbia as a contributor to the connectivity of Sardinia with the rest of Italy, rather than as an entry point for international traffic. The landing point is served by one established cable dating to 2005 and one forthcoming cable scheduled for 2025, indicating ongoing investment in the capacity available to this part of northeastern Sardinia.
As an island landing point operating within a purely domestic cable corridor, Olbia illustrates the role that submarine cables play in bridging Italian island territories to the mainland network. Its position in the broader Italian submarine cable graph reflects how even mid-sized cities in island regions depend on undersea infrastructure to supplement or replace terrestrial connectivity options.
