Port Erin, Isle of Man

Port Erin, Isle of Man: Submarine Cable Landing Point

Port Erin is a seaside village situated in the south-west of the Isle of Man, in the historic parish of Rushen. As an island territory in the Irish Sea, the Isle of Man depends entirely on submarine cable connections to maintain its communications links with neighbouring countries, making each landing point on the island a point of meaningful connectivity. Port Erin serves as one of five submarine cable landing points across the Isle of Man, hosting one submarine cable that connects the island to Ireland and the United Kingdom.

The cable landing at Port Erin is Havhingsten/CeltixConnect-2 (CC-2), a regional system that spans waters between the Isle of Man, Ireland, and the United Kingdom. This cable positions Port Erin within a short-range, inter-island and cross-sea corridor rather than an intercontinental one, reflecting the relatively compact scale of Irish Sea connectivity infrastructure.

Cables Landing at Port Erin, Isle of Man

Havhingsten/CeltixConnect-2 (CC-2) is a submarine cable system measuring 301 kilometres in length, which became ready for service in 2022. The cable connects the Isle of Man with Ireland and the United Kingdom, forming a triangular route across the Irish Sea. It is among the more recently deployed systems in the region and represents a modern addition to the Isle of Man's submarine cable infrastructure.

Regional Context

Within the Isle of Man, Port Erin is one of five landing points hosting a combined total of six submarine cables. With one cable, Port Erin ranks alongside Douglas and Groudle Bay, each of which also hosts a single cable, while Peel and Port Grenaugh each accommodate two cables, making them the more connected landing points on the island. Port Erin therefore sits in the middle tier of the Isle of Man's cable landing geography by cable count.

Network Role

Port Erin functions as a single-cable terminus, providing a dedicated link between the Isle of Man and two neighbouring territories — Ireland and the United Kingdom — via the Havhingsten/CeltixConnect-2 system. This connection contributes to the overall resilience of the Isle of Man's external submarine cable network by distributing landing points around the island's coastline, rather than concentrating all connectivity in a single location.

In the broader submarine cable graph of the Irish Sea region, Port Erin's role is that of a specialised endpoint on a short-range regional cable. Its presence as a distinct landing point, separate from the island's other cable terminals, adds geographic diversity to the Isle of Man's undersea communications architecture.
