St. Ouens Bay, Jersey: Submarine Cable Landing Point

St. Ouens Bay is a submarine cable landing point located in the parish of St. Ouen, Jersey, one of the Channel Islands situated in the waters between the United Kingdom and the northwestern coast of France. The bay sits on the northwestern edge of Jersey, part of the island's exposed Atlantic-facing coastline. One submarine cable makes landfall here, connecting Jersey to the United Kingdom and forming part of the island's external telecommunications infrastructure.

The single cable landing at St. Ouens Bay, the UK-Channel Islands-8, links Jersey directly to the United Kingdom. This connection places the landing point within a short-haul, inter-island and island-to-mainland corridor, serving the Channel Islands region rather than spanning intercontinental distances. The cable has been in service since 1994, making St. Ouens Bay one of Jersey's longest-established submarine cable landing sites.

Cables Landing at St. Ouens Bay, Jersey

The UK-Channel Islands-8 is the sole submarine cable landing at St. Ouens Bay. The cable measures 237 kilometres in length and reached ready-for-service status in 1994. Its route connects Jersey to the United Kingdom, providing a direct submarine link between the island and its closest major neighbour. The cable was classified with a draft status at the time of record.

Regional Context

Jersey's submarine cable infrastructure is shared across two landing points: St. Ouens Bay and Greve de Lecq, each hosting one submarine cable. Together, these two sites account for all submarine cable connectivity reaching Jersey, with an average cable length of 137 kilometres across the island's two connections. St. Ouens Bay's cable, at 237 kilometres, is the longer of the two and also the earliest, with its 1994 RFS date marking the beginning of Jersey's recorded submarine cable history.

Network Role

St. Ouens Bay functions as a single-cable terminus rather than a multi-cable hub, hosting one route that runs exclusively between Jersey and the United Kingdom. This places it within a short regional corridor that provides the island with a direct submarine pathway to UK landing infrastructure. The UK-Channel Islands-8 cable, now several decades in service, represents the foundational layer of submarine connectivity that was established at this location.

Within the broader submarine cable graph of the Channel Islands region, St. Ouens Bay's role is defined by its pairing with Greve de Lecq as one of only two cable landing points on the island of Jersey, together forming the complete set of submarine entry points through which the island's external cable capacity flows.
