Oskarshamn, Sweden: Submarine Cable Landing Point

Oskarshamn is a coastal city in Kalmar County, southeastern Sweden, and the seat of Oskarshamn Municipality. Situated along the Baltic Sea coast, the city serves as a submarine cable landing point within Sweden's broader network of 28 submarine cable landings spread across 28 locations. One submarine cable lands at Oskarshamn, connecting the city to another point within Sweden and contributing to domestic connectivity in the Baltic corridor.

The single cable landing here, Oskarshamn-Visby, links the Swedish mainland directly to the island of Visby on Gotland. This makes the connection an intra-national, inter-island route rather than an intercontinental or international link. The cable enables direct seabed-based communication between the Swedish mainland coast and one of Sweden's most geographically distinct island communities.

Cables Landing at Oskarshamn

Oskarshamn-Visby entered readiness for service in 2008 and currently holds draft status. The cable connects Oskarshamn on the Swedish mainland to Visby, the principal settlement on the island of Gotland, with both endpoints located within Sweden. No additional countries are served by this cable. Its route traverses the Baltic Sea between the mainland and the island, providing a dedicated submarine link for this domestic corridor.

Regional Context

Within Sweden's submarine cable infrastructure, Oskarshamn ranks among the smaller landing points by cable count, hosting one cable compared to multi-cable hubs such as Farosund, Stockholm, and Visby, each of which land three cables. Peers including Capri Strand, Helsingborg, and Klagshamn each host two cables, placing Oskarshamn at the lower end of the country's landing point hierarchy. With its single domestic cable, Oskarshamn occupies a specialised rather than aggregated role in Sweden's submarine network.

Network Role

Oskarshamn functions as a single-cable terminus, serving specifically as the mainland anchor point for the Oskarshamn-Visby connection. Rather than acting as a multi-cable hub aggregating diverse routes, its role is focused: providing the mainland side of a direct submarine link to Gotland. The Oskarshamn-Visby cable is part of a domestic inter-island corridor that also involves Visby itself, which hosts additional cables connecting Gotland to other Swedish landing points.

In the broader Swedish submarine cable graph, Oskarshamn represents one of several mainland entry points that extend seabed connectivity to island communities, demonstrating how Sweden's distributed network of 28 landing points serves both continental and insular portions of the country's territory.
