Ponce, PR, United States: Submarine Cable Landing Point

Ponce is a city on the southern coast of Puerto Rico, a United States territory in the Caribbean Sea. As the most populated city on Puerto Rico's southern shore, Ponce serves as a submarine cable landing point connecting the island to a broader network of Caribbean and Latin American connectivity. One submarine cable lands at Ponce, linking it to a corridor that spans Central America, South America, Mexico, and the wider Caribbean.

The single cable landing at Ponce is the America Movil Submarine Cable System-1 (AMX-1), a major intercontinental system that ties Ponce into a loop encompassing multiple countries across the Western Hemisphere. The cable's reach—extending to Brazil in South America, through Colombia, Costa Rica, Guatemala, Mexico, and the Dominican Republic—means Ponce functions as a Caribbean node on a route with significant geographic range across the Americas.

Cables Landing at Ponce, PR, United States

The America Movil Submarine Cable System-1 (AMX-1) is 17,800 km in length and reached ready-for-service (RFS) status in 2014. In addition to Ponce, the system connects to landing points in Brazil, Colombia, Costa Rica, the Dominican Republic, Guatemala, and Mexico. This routing positions AMX-1 as an intercontinental cable spanning both the Caribbean Sea and significant portions of the Atlantic and Pacific coastal routes of Latin America. Ponce represents Puerto Rico's southern landing on this system, complementing the cable's broader multi-country architecture.

Regional Context

Within the United States submarine cable landscape, which encompasses 113 cables across 160 landing points, Ponce hosts one cable and ranks in the top 69% of U.S. landing points by cable count. Compared to other U.S. landing points such as Boca Raton, FL, and San Juan, PR, each of which host eight cables, or Hermosa Beach, CA, and Kapolei, HI, each with five, Ponce is a more focused landing point with a single system connecting it to the region. Within Puerto Rico itself, San Juan on the island's northern coast is a considerably more cable-dense hub.

Network Role

Ponce operates as a single-cable terminus on the southern coast of Puerto Rico, contributing to the AMX-1 system's multi-country loop through Latin America and the Caribbean. Its position on the island's southern shore provides geographic diversity relative to Puerto Rico's northern landing points, offering an alternative coastal entry point for the AMX-1 system's routing through the Caribbean corridor.

In the regional submarine cable graph, Ponce's role is defined by its participation in a long-haul, multi-country system connecting the Caribbean to Central and South America, situating Puerto Rico's southern coast within a network that otherwise would be served only from the island's northern approaches.
