Naousa, Greece: Submarine Cable Landing Point

Naousa is a city in the Imathia regional unit of Central Macedonia, in northern Greece, situated at the foot of the Vermio Mountains. As a submarine cable landing point, it connects to Greece's broader intra-national cable network, with three submarine cables making landfall here. All three cables link Naousa to other points within Greece, establishing it as a node in the domestic Greek submarine cable corridor rather than an intercontinental gateway.

The three cables landing at Naousa — Thetis, Cyclades A, and Cyclades B — collectively form an entirely intra-Greek network of connections. This pattern positions Naousa as a landing point oriented toward inter-island and domestic mainland connectivity, supporting the internal fabric of Greece's submarine cable infrastructure across regional and island routes.

Cables Landing at Naousa

Thetis is a submarine cable measuring 660 km in length, with a ready-for-service (RFS) date of 2022. The cable connects landing points within Greece, making it the longest of the three cables at Naousa and the most recently completed at the time of its commissioning.

Cyclades A is a submarine cable measuring 222 km in length, with an RFS date of 2018. Like Thetis, it connects endpoints exclusively within Greece, forming part of the intra-national cable network that serves the Greek archipelago and coastal regions.

Cyclades B is the shortest of the three cables landing at Naousa, at 52 km in length, with an RFS date of 2020. It also connects points within Greece, rounding out a trio of domestically oriented submarine links at this landing point.

Regional Context

Among Greece's 36 submarine cable landing points, Naousa hosts three cables, placing it alongside Mykonos as a mid-tier landing point by cable count. It trails larger hubs such as Chania (5 cables), Athens (4 cables), and Tympaki (4 cables), while hosting more cables than peers such as Aethos and Ermoupoli, each of which serves two cables. With three cables, Naousa ranks in the top 92% of Greek landing points by cable count.

Network Role

Naousa functions as a multi-cable landing point within Greece's domestic submarine cable network, terminating three intra-national cables that span a combined route length from 52 km to 660 km. All three cables — Thetis, Cyclades A, and Cyclades B — connect exclusively to other Greek endpoints, meaning Naousa's role is oriented toward internal Greek connectivity rather than toward international or intercontinental traffic. The cables arrived in successive waves between 2018 and 2022, reflecting sustained investment in domestic Greek submarine infrastructure during that period.

Within the regional submarine cable graph, Naousa's three intra-Greek cables contribute to the redundancy and reach of Greece's internal network, linking a mainland city in Central Macedonia to routes that traverse the country's island-dense southern waters.
