TT1

Overview

TT1 is a short intra-national submarine cable system serving Trinidad and Tobago. With a total length of 44 km, it connects two landing points within the same country, making it one of the shortest cables in the Caribbean corridor. The system links Pigeon Point and Toco, both located in Trinidad and Tobago, providing a domestic submarine connection within the twin-island nation.

Route and Landings

Both landing points on the TT1 cable are situated in Trinidad and Tobago. The cable comes ashore at Pigeon Point and at Toco, two geographically distinct coastal locations within the country. The 44 km route between these two points serves as an undersea link between different parts of the island nation.

Ownership and Operators

TT1 is jointly owned by three entities: Alliance Telecommunications, Liberty Networks, and TSTT. TSTT (Telecommunications Services of Trinidad and Tobago) is the national telecommunications provider of Trinidad and Tobago. The shared ownership structure reflects the interests of both domestic and regional telecommunications operators in maintaining connectivity within the country.

Status and Timeline

TT1 entered service in 2015 and has been operational for approximately 11 years. The cable continues to serve its domestic route between Pigeon Point and Toco.

Regional Context

Trinidad and Tobago is served by six submarine cables landing across four landing points. The cables active in this corridor vary considerably in scale and reach. TT1, at 44 km, is the shortest among its peers in the region. By comparison, regional cables touching Trinidad and Tobago include Southern Caribbean Fiber at 3,000 km, Deep Blue One at 2,250 km, the Eastern Caribbean Fiber System at 1,730 km, the Suriname-Guyana Submarine Cable System at 1,249 km, and EC Link at 1,078 km. TT1 is notably shorter than all five of these systems, reflecting its strictly domestic purpose rather than inter-island or intercontinental reach.

Strategic Role

TT1 provides a submarine connection between two separate coastal locations within Trinidad and Tobago. Its domestic scope — linking Pigeon Point and Toco — distinguishes it from the longer regional systems that connect Trinidad and Tobago to other Caribbean territories or continental landmasses. The cable supports internal connectivity for the twin-island nation, complementing the broader set of international cables that land in Trinidad and Tobago.
