Deep Blue One

Overview

Deep Blue One is a regional submarine cable system spanning approximately 2,250 km across the northeastern coast of South America and the southern Caribbean. It connects French Guiana, Guyana, Suriname, and Trinidad and Tobago, serving a corridor that links several smaller national markets along the Guiana Shield coastline with Trinidad and Tobago as a connectivity hub.

Route and Landings

In French Guiana, the cable lands at Cayenne. In Guyana, it comes ashore at Georgetown, the country's capital. Paramaribo, the capital of Suriname, serves as the cable's landing point in that country. Trinidad and Tobago has two landing stations on the system: Chaguaramas and Rockly Bay, the latter located on the island of Tobago.

Ownership and Operators

Deep Blue One is owned solely by Digicel, the Caribbean-focused telecommunications group with operations across the Caribbean and Pacific regions. As the sole owner, Digicel both funded and controls the cable system.

Status and Timeline

Deep Blue One entered service in 2024, making it one of the more recently commissioned cable systems in the southern Caribbean and Guiana coast corridor.

Regional Context

The northeastern South American coastal corridor has seen several submarine cable deployments over the years. The Suriname-Guyana Submarine Cable System (SG-SCS), which also serves Guyana, Suriname, and Trinidad and Tobago, became ready for service in 2010 and spans 1,249 km. Deep Blue One, at 2,250 km and ready for service in 2024, extends coverage to French Guiana and adds a second landing in Trinidad and Tobago through Rockly Bay, alongside established systems such as Southern Caribbean Fiber and EC Link, which serve Trinidad and Tobago. The Kanawa cable, ready for service in 2019, also reaches French Guiana at a shorter length of 1,746 km. Deep Blue One therefore represents a newer addition to a corridor served by multiple cable systems of varying age and scale.

Strategic Role

By landing at two points in Trinidad and Tobago — Chaguaramas and Rockly Bay — and connecting three Guiana coast nations to those hubs, Deep Blue One supports redundancy and broader geographic reach within the region. The inclusion of both Georgetown and Paramaribo alongside Cayenne gives each of the three continental landing countries direct submarine connectivity under a single cable system, reducing reliance on any single existing route for traffic between these markets and Trinidad and Tobago.
