EllaLink has officially launched the Caribbean Gateway project to connect French Guiana and the Caribbean to Europe, Brazil, and North America. The initiative is currently moving from the design phase to committed investment, with the system targeted for completion by the end of 2029.

Why it matters

The project addresses growing capacity demands and serves regional objectives for resilient submarine infrastructure as current networks face phase-out by 2031. It provides a fully diverse path for territories currently reliant on single international corridors.

The existing EllaLink trunk currently delivers 100 Tbps of capacity with a 60 ms round-trip latency across its 9,400 km network. This new expansion integrates a 2,100 km extension known as Lum@link, which received a EUR 29.9 million grant to facilitate the connection.

The players

EllaLink

An operator of submarine cable infrastructure focused on high-capacity, low-latency data routes connecting Europe and Latin America.

The details

The infrastructure model functions by EllaLink designing and building the submarine segments before transferring branch ownership to local landing parties. This system links Cayenne to hubs in Martinique and Guadeloupe, with additional segments serving Aruba, Curaçao, and Bonaire. By converting letters of intent into firm commitments, the company creates a decentralized ownership structure for the cable branches.

Timeline

  1. June 2021: EllaLink trunk between Portugal and Brazil entered service.

  2. February 2026: Porto Declaration on submarine cable resilience was signed.

  3. September 29, 2026: Caribbean Gateway initiative was officially launched.

  4. End of 2026: Lum@link extension is expected to be ready for service.

  5. End of 2029: Caribbean Gateway system is targeted to be ready for service.

The Tech Race

The Caribbean Gateway project follows the infrastructure standards established in the Porto Declaration on submarine cable resilience. It marks a departure from reliance on singular, aging corridors by building new, fully diverse paths in a region where current systems are scheduled to phase out by 2031.

This project will improve network resilience and data capacity for businesses and residents throughout the Caribbean by adding redundant, high-speed routes. While the full system is slated for 2029, initial capacity increases will begin when the Lum@link segment goes live in 2026.

The takeaway

The Caribbean Gateway represents a strategic attempt to modernize submarine infrastructure before a wave of systemic legacy cable retirements occurs by 2031. Stakeholders should track the 2026 service readiness date for Lum@link as a benchmark for the project's construction velocity.

What happens next

The Lum@link extension is scheduled to be ready for service by the end of 2026, followed by the full Caribbean Gateway system by the end of 2029.
