Eastern Caribbean Fiber System (ECFS)

Overview

The Eastern Caribbean Fiber System (ECFS) is a regional submarine cable network spanning 1,730 kilometres across the Eastern Caribbean. It connects thirteen territories throughout the Lesser Antilles, running through Anguilla, Antigua and Barbuda, Barbados, Dominica, Grenada, Guadeloupe, Martinique, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Sint Maarten, Trinidad and Tobago, and the British Virgin Islands. The system provides intra-Caribbean connectivity across a broad arc of island nations and territories.

Route and Landings

In Anguilla, the cable lands at The Valley. In Antigua and Barbuda, it comes ashore at St. John's. Barbados is served by a landing at Bridgetown, while Dominica's landing point is Roseau. In Grenada, the cable reaches Point Salines, and in Guadeloupe it lands at Pointe-à-Pitre. Martinique is served by Le Lamentin. Saint Kitts and Nevis has a landing at Frigate Bay, and Saint Lucia at Castries. Kingstown serves as the landing point in Saint Vincent and the Grenadines. Sint Maarten is connected via Saint Maarten, and Trinidad and Tobago through Chaguaramas. In the British Virgin Islands, the cable lands at Tortola.

Ownership and Operators

The ECFS is owned by a consortium of six companies: AT&T, Claro Dominicana (Codetel), Guyana Telephone and Telegraph (GT&T), Liberty Networks, Orange, and Verizon. This ownership structure reflects broad participation from both US-based telecommunications carriers and regional operators serving the Eastern Caribbean market.

Status and Timeline

The Eastern Caribbean Fiber System entered service in 1995, making it one of the earlier fibre optic submarine cable systems deployed in the Caribbean region. The system currently remains in service, providing connectivity across its thirteen landing points.

Regional Context

The Eastern Caribbean corridor has seen considerable submarine cable investment over the decades since ECFS entered service. Regional peers active in overlapping portions of this corridor include the Southern Caribbean Fiber system, which shares landings in Antigua and Barbuda, Barbados, Dominica, Grenada, Guadeloupe, Martinique, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, and Trinidad and Tobago, and was ready for service in 2006. More recent additions include East-West Cable serving the British Virgin Islands, Kanawa and ARIMAO serving Martinique, and Deep Blue One serving Trinidad and Tobago. The forthcoming CELIA system, planned for 2027, will further expand capacity in the Antigua and Barbuda–Martinique segment. ECFS predates all of these systems, having established fibre connectivity across thirteen Eastern Caribbean territories nearly three decades before several of its neighbours were deployed.

Strategic Role

With landings across thirteen distinct territories, the Eastern Caribbean Fiber System provides a wide-reaching intra-Caribbean fibre infrastructure spanning from the British Virgin Islands and Sint Maarten in the north to Trinidad and Tobago in the south. Its extensive landing footprint across both independent states and overseas territories of France, the Netherlands, and the United Kingdom reflects the diverse political geography of the Eastern Caribbean, and the system continues to serve as a long-standing fibre link among these islands.
