Kalafati, Greece: Submarine Cable Landing Point

Kalafati is a coastal location in Greece that serves as a submarine cable landing point. Greece as a whole hosts 13 submarine cables across 30 landing points, and Kalafati is among those that host a single cable connection. As the landing point for the Thetis cable, Kalafati participates in a domestic Greek submarine cable corridor, linking locations within the country rather than serving intercontinental or cross-border routes.

With one submarine cable landing here, Kalafati represents a focused node in the Greek submarine cable network. The Thetis cable, which connects Greek endpoints, establishes an intra-national link that contributes to domestic connectivity across the country's extensive island and coastal geography.

Cables Landing at Kalafati

Thetis is a 660-kilometre submarine cable with a Ready for Service (RFS) date of 2022, currently noted as a draft system. The cable connects endpoints exclusively within Greece, making it a domestic route rather than an international crossing. At 660 kilometres, Thetis is considerably shorter than the Greek average cable length of 3,317 kilometres, reflecting its role as a regional intra-country link rather than a long-distance intercontinental system.

Regional Context

Within Greece's 30 submarine cable landing points, Kalafati ranks in the top 90 percent by cable count, hosting one cable alongside peers such as Aethos, Agios Sostis, and Baxedes, each of which also hosts a single cable. By comparison, Chania leads the Greek network with five cables, followed by Athens with four and Tympaki with three, positioning Kalafati as one of several single-cable landing points that complement the country's busier hubs.

Network Role

Kalafati functions as a single-cable terminus in the Greek submarine cable graph, serving as one endpoint of the domestic Thetis system. Rather than acting as a multi-cable hub with diverse international connections, Kalafati contributes to intra-national connectivity, supporting data routing between Greek locations across a 660-kilometre route. The Thetis cable's draft status as of its 2022 RFS date indicates this is a recently established connection, adding a newer link to Greece's submarine cable infrastructure.

In the broader context of Greece's submarine network, single-cable landing points such as Kalafati play a supporting role by extending connectivity to locations that are not served by the country's larger hub nodes. The presence of a domestically oriented cable at Kalafati reinforces the distributed character of Greece's submarine cable geography, where connectivity reaches across numerous coastal and island locations through a combination of international corridors and shorter intra-national links.
