The Southern Caribbean Fiber is a game-changer for the region, providing a high-speed internet connection that's long overdue. This underwater cable spans over 1,400 kilometers, connecting several islands in the Southern Caribbean.
The fiber optic cable reduces latency and increases bandwidth, making it ideal for online activities like streaming and online gaming. This is especially important for the tourism industry, which relies heavily on internet connectivity to attract visitors.
The cable's design allows for easy maintenance and upgrades, ensuring that it remains a reliable and efficient connection for years to come. This is a welcome relief for businesses and residents who have struggled with slow internet speeds in the past.

The Southern Caribbean Fiber (SCF) is a submarine cable that connects 15 islands in the Eastern Caribbean with 16 landing points.

The SCF cable system is owned and operated by Southern Caribbean Fiber (SCF), a subsidiary of Digicel Group.
The SCF cable system consists of two main branches: the omnibus branch, which connects Trinidad to St-Croix and Puerto Rico, and the express branch, which connects Barbados to St-Lucia and St-Croix.
The omnibus branch is a repeaterless system made up of submarine cable comprising 4 to 8 fiber pairs, supplied by Alcatel Submarine Networks (ASN).
The express branch is a repeated submarine cable made up of 2 fiber pairs covering approximately 900 km, supplied by Tyco (now SubCom).
Here are the key features of the SCF cable system:
- Omnibus branch: connects Trinidad to St-Croix and Puerto Rico, repeaterless system with 4-8 fiber pairs
- Express branch: connects Barbados to St-Lucia and St-Croix, repeated submarine cable with 2 fiber pairs
The SCF cable system participates in the Atlantic Cable Maintenance Agreement (ACMA) for the maintenance of the wet plant of the SCF cable system.
In 2019, SCF signed a $5.9 million agreement with the government of Montserrat for the installation and operation of a new submarine fibre-optic cable system connecting Guadeloupe and Antigua.
Deep Blue Goes Live

Digicel's new subsea fibre cable Deep Blue One is now live, connecting French Guiana, Suriname, Guyana, and Trinidad & Tobago.
Deep Blue One is a 2,000-km subsea cable with a minimum capacity of 12 Tbps per fibre pair.
The cable has five branching units, with two to eight fibre pairs per segment.
It was developed and built by Digicel in partnership with Orange, which owns a fibre pair on the system.
Orange is also providing landing facilities in French Guiana.
The system interconnects with Orange's Kanawa subsea cable that runs between French Guiana and Martinique.
It also connects with Digicel's existing Southern Caribbean Fiber (SCF) system, which has reportedly been rebranded as Deep Blue.
This new cable presents an opportunity for Digicel to connect offshore oil and gas rigs in the region.
The growing energy sector in the region is expected to benefit from this connectivity.
According to Digicel CEO Marcelo Cataldo, "Subsea fibre has long been the backbone of global connectivity, and Deep Blue One is set to serve as a catalyst for the next wave of economic development in the region."
