Dominican Republic
The Dominican Republic connects to the global internet through four active submarine cables, reflecting its position as one of the better-served nations in the Caribbean — though landing point documentation remains incomplete.

Submarine connectivity overview
The Dominican Republic sits on the island of Hispaniola, shared with Haiti, in the northern Caribbean. That geography places it within reach of cable routes threading through the Caribbean Sea and connecting to the United States, Central America, South America, and beyond. Four active submarine cable systems serve the country, a count that compares favourably with many of its island neighbours and suggests meaningful redundancy — though the practical resilience of any network depends on where cables land, how they route, and who operates them.
The cable mix
The four systems on record — AMX-1, ANTILLAS I, ARCOS-1, and Fibralink — represent a mix of regional and international reach. AMX-1, which entered service in 2014, is part of a large loop system operated by Mexican telecommunications group América Móvil, connecting multiple countries across Latin America and the Caribbean to the United States. ARCOS-1 is a regional ring system spanning the Caribbean and Central America, historically one of the primary submarine infrastructure backbones for the island Caribbean. ANTILLAS I and Fibralink are smaller or more regionally scoped systems, though detailed specifications for both remain under compilation in this register.
Taken together, the four cables point toward a reasonable diversity of operators and routes rather than dependence on a single system. Multiple cable owners reduce the risk that a commercial disruption to one operator leaves the country without alternatives. Multiple physical routes reduce, though never eliminate, the risk of simultaneous outage from a single cable fault.
Geography and resilience
Hispaniola's position in the Greater Antilles corridor means cables approaching the Dominican Republic must navigate relatively shallow shelf areas and the complex bathymetry of the Caribbean basin — conditions that influence both route design and fault exposure. The island's size and the presence of a land border with Haiti also raise questions about whether terrestrial infrastructure plays any role in cross-border connectivity, though submarine cables remain the foundation of international bandwidth for the country.
Landing point data
No landing points for the Dominican Republic are yet documented in this register. Landing point data — the precise coastal locations where cable systems come ashore — is essential for understanding true network resilience, since cables sharing a landing station lose their diversity value in a single physical event. This register is actively compiling that information. Operators, researchers, or officials with landing point details are encouraged to contribute through the site's submissions process.
