Miquelon-Langlade, Saint Pierre and Miquelon: Submarine Cable Landing Point

Miquelon-Langlade is a landing point located in Saint Pierre and Miquelon, a French territorial collectivity situated off the southern coast of Newfoundland, Canada. As a submarine cable landing point, it forms part of the small but significant cable infrastructure that connects this island territory to the North American mainland. One submarine cable lands at Miquelon-Langlade, linking Saint Pierre and Miquelon directly to Canada and enabling a regional corridor across a relatively short stretch of the North Atlantic.

The cable serving Miquelon-Langlade is the St. Pierre and Miquelon Cable, which represents the territory's submarine connectivity infrastructure commissioned in 2018. The route it enables is a short-haul, regional connection between the islands of Saint Pierre and Miquelon and Canada, spanning approximately 200 kilometres. This positions Miquelon-Langlade as a landing point supporting inter-island and mainland connectivity rather than intercontinental traffic.

Cables Landing at Miquelon-Langlade

The St. Pierre and Miquelon Cable is the sole submarine cable landing at Miquelon-Langlade. Measuring approximately 200 kilometres in length, this cable reached its ready-for-service date in 2018, though its status at that time was noted as draft. The cable connects Saint Pierre and Miquelon with Canada, making it a direct regional link between the French territorial collectivity and its nearest major landmass neighbour. Miquelon-Langlade serves as one of the cable's termination points within Saint Pierre and Miquelon, with the route providing the island group a tangible physical connection to North American cable infrastructure.

Regional Context

Within Saint Pierre and Miquelon, Miquelon-Langlade shares the territory's submarine cable landscape with one other landing point: Saint-Pierre. Each landing point hosts a single cable, together accounting for the entirety of Saint Pierre and Miquelon's two-landing-point submarine cable infrastructure. Miquelon-Langlade and Saint-Pierre together reflect the modest but complete coverage of the territory's coastline for submarine cable connectivity.

Network Role

Miquelon-Langlade functions as a single-cable terminus, anchoring one end of the St. Pierre and Miquelon Cable on the Miquelon-Langlade island. The cable it hosts establishes a direct physical link between this part of the territory and Canada, providing a regional connection across a 200-kilometre span that became active in 2018. This makes Miquelon-Langlade a terminus point rather than a transit or multi-cable hub within the broader submarine cable network.

In the regional submarine cable graph, Miquelon-Langlade's role is specific and bounded: it extends cable connectivity to the Miquelon-Langlade portion of the territory, complementing the Saint-Pierre landing point and ensuring that submarine cable infrastructure reaches beyond a single island within this French territorial collectivity.
