EllaLink has moved its Caribbean Gateway submarine cable from design to committed investment, targeting ready-for-service by the end of 2029 on a new system that runs from Cayenne, French Guiana, to Martinique and Guadeloupe, with a western segment serving Aruba, Curaçao and Bonaire.

The company positions the EllaLink Caribbean Gateway (ECG) as an open, carrier-neutral corridor offering a tailored connectivity solution to every territory it serves. Each territory will connect either by its own branch and landing from the trunk or through interconnection in Martinique, with express connectivity in three directions: to continental Europe over the EllaLink transatlantic system, to Fortaleza in Brazil — one of the largest cable hubs in the world — and onwards to North America.

The launch of the development phase means the project now moves from design to committed investment. Over the coming months, EllaLink will convert letters of intent into firm commitments with the landing parties along the route, complete the financing package and close the funding structure that allows construction to start.

Why the corridor matters

For territories that today depend on a single international corridor, often reached through several hops, the EllaLink Caribbean Gateway adds a fully diverse path. It also offers more direct access to the cloud, content and interconnection ecosystems of three continents.

By adding a new route that complements the systems already in place, the gateway gives governments and operators more choice, more diversity and a long-term option for their future capacity needs, according to the operator.

A branch model that keeps EllaLink out of the retail market

EllaLink says it applies to the Caribbean Gateway the economic model it already used for dedicated branches in Morocco, Mauritania, Madeira, Cape Verde and French Guiana. The structure matters for the commercial calculus of prospective landing parties: EllaLink designs and builds the infrastructure, then transfers ownership of the branch to the landing party and operates and maintains it for the life of the system.

The landing party owns its branch, holds a dedicated spectrum IRU (indefeasible right of use) on the trunk and sets the capacity access policy on its own territory, deciding how capacity is allocated and commercialised locally. EllaLink stresses it does not sell capacity on these branches and does not compete with the customers it serves — a distinction that separates the venture from wholesale carriers that retain control of branch capacity and resell it themselves.

Built on the Lum@link extension

The technical foundation for the Caribbean corridor is already under construction. The EllaLink trunk between Sines, Portugal, and Fortaleza, Brazil — first reported in 2019 and in service since June 2021 — has grown from a single route into a network of more than 9,400 kilometres, with extensions to Madeira, Cape Verde, Morocco and Mauritania.

The most recent addition, the Lum@link extension of approximately 2,100 kilometres, connects the new cable landing station in Cayenne to the EllaLink trunk 250 km off the coast of Fortaleza. EllaLink says Lum@link is what makes the ECG possible: from the end of this year, Cayenne becomes a European landing point on the South American continent, with direct optical connections to both Fortaleza and Sines, and the natural origin for a corridor running north into the Caribbean.

That timing gives the project a concrete sequencing logic: once Cayenne is live as a European landing point at the end of this year, the Caribbean Gateway can extend north from an established hub rather than depending on a future connection point.

The road to 2029

The immediate milestones are contractual and financial rather than marine. Converting letters of intent into firm commitments with landing parties, completing the financing package and closing the funding structure are the stated next steps before construction can begin. The end-2029 ready-for-service target gives the territories involved — several of which currently rely on a single international corridor — a multi-year timeline for planning capacity strategies around a second, diverse path into Europe, Brazil and North America.
