Jarry, Guadeloupe: Submarine Cable Landing Point

Jarry is a landing point located in Guadeloupe, the French overseas department and region situated in the Lesser Antilles of the Caribbean. Positioned within the industrial zone of Baie-Mahault, Jarry forms part of the broader urban area of Pointe-à-Pitre on the island's western coast. One submarine cable lands at Jarry, connecting Guadeloupe into a regional Caribbean corridor that spans several island territories and extends to the United States mainland.

The single cable serving Jarry is the Global Caribbean Network (GCN), a system that links Guadeloupe with Saint Barthélemy, Saint Martin, the United States Virgin Islands, and the United States. This configuration places Jarry within a corridor that is primarily regional and inter-island in character, facilitating connectivity between French and American Caribbean territories as well as a direct link toward the North American mainland.

Cables Landing at Jarry, Guadeloupe

The Global Caribbean Network (GCN) is an 890-kilometre submarine cable system that reached ready-for-service status in 2006. In addition to Jarry in Guadeloupe, the GCN connects to Saint Barthélemy, Saint Martin, the United States Virgin Islands, and the United States. The system weaves through several of the northern Lesser Antilles and the Virgin Islands chain before terminating on the US mainland, forming a multi-territory ring across the northeastern Caribbean.

Regional Context

Guadeloupe hosts four submarine cables distributed across nine landing points, and Jarry is among the majority of those points served by a single cable. Baillif stands out as the most connected landing point in the territory with two cables, while Baie-Mahault, Beausejour, Capesterre-Belle-Eau, Pointe-à-Pitre, and Saint-François each share the same single-cable profile as Jarry. Within this distributed national topology, Jarry represents one of several landing points that together spread Guadeloupe's submarine cable access across multiple communities and coastlines.

Network Role

Jarry functions as a single-cable terminus on the GCN system, providing a connection point that links Guadeloupe northward through Saint Barthélemy and Saint Martin to the Virgin Islands and onward to the United States. While it does not operate as a multi-cable hub, its placement on a system that traverses multiple Caribbean jurisdictions means that Jarry participates in a broader inter-island and transatlantic-adjacent corridor rather than serving purely local connectivity. The GCN's 2006 ready-for-service date positions Jarry's infrastructure within Guadeloupe's more recent wave of submarine cable development, given that the territory's first cable dates to 1995.

Within the regional submarine cable graph, Jarry's significance lies in the geographic diversity it adds to Guadeloupe's landing point distribution, ensuring that the industrial zone of Baie-Mahault — the most industrialised area in the Lesser Antilles — maintains a direct physical connection to the Caribbean and North American cable network.
