Santo Domingo, Dominican Republic: Submarine Cable Landing Point

Santo Domingo is the capital and largest city of the Dominican Republic, situated on the southern coast of the island of Hispaniola. As the country's primary metropolitan center, it is one of five submarine cable landing points distributed across the Dominican Republic. One submarine cable lands at Santo Domingo, connecting the city directly into a wide Latin American and Caribbean network corridor.

That cable, the America Movil Submarine Cable System-1 (AMX-1), links Santo Domingo to a broad set of endpoints spanning Central and South America, placing the city within a regional framework that connects multiple Atlantic and Pacific-facing nations. The AMX-1 system enables connectivity between the Dominican Republic and countries including Brazil, Colombia, Costa Rica, Guatemala, and Mexico, forming a corridor that spans both the Caribbean Sea and significant portions of the wider Western Hemisphere.

Cables Landing at Santo Domingo

The America Movil Submarine Cable System-1 (AMX-1) is a submarine cable system measuring 17,800 km in total length, which reached ready-for-service (RFS) status in 2014. In addition to its landing at Santo Domingo in the Dominican Republic, the cable connects Brazil, Colombia, Costa Rica, Guatemala, and Mexico. This extensive network of endpoints positions AMX-1 as a long-haul intercontinental system traversing Caribbean and Latin American waters, linking the Dominican Republic to both Central American and South American cable segments within a single integrated system.

Regional Context

Within the Dominican Republic, Santo Domingo is one of five landing points, alongside Puerto Plata, Punta Cana, Cacique, and Haina. Puerto Plata and Punta Cana each host three cables, making them the most connected landing points in the country by cable count, while Santo Domingo, Cacique, and Haina each host a single cable. Despite serving as the national capital, Santo Domingo ranks in the middle tier of the country's landing points by number of cables, reflecting how submarine cable infrastructure in the Dominican Republic is distributed across multiple coastal sites rather than concentrated at a single urban hub.

Network Role

Santo Domingo functions as a single-cable terminus in the Dominican Republic's submarine cable map. Through the AMX-1 system, it provides a direct international link to five other countries across Latin America and the Caribbean, enabling connectivity to destinations stretching from Mexico in North America to Brazil in South America. The cable's 2014 RFS date makes it a relatively recent addition to the country's international cable infrastructure, which first began developing in 1997.

In the broader regional submarine cable graph, Santo Domingo's participation in a 17,800 km intercontinental system means that the capital city connects to nodes well beyond the Caribbean basin, extending westward and southward through Central and South American landings. This positions Santo Domingo as a distinct corridor endpoint within the Dominican Republic, complementing the multi-cable landing points at Puerto Plata and Punta Cana on the country's northern and eastern coasts.
