Jacksonville, FL: Submarine Cable Landing Point

Jacksonville, Florida, sits on the Atlantic coast of northeastern Florida and serves as a submarine cable landing point connecting the continental United States to the Caribbean Basin and Latin America. Three submarine cables land at Jacksonville, making it a notable node on the eastern seaboard of the United States. The cables here collectively reach destinations across the Caribbean, Central America, and South America, supporting a corridor that spans both intercontinental and regional connectivity.

Among the cables landing at Jacksonville, the America Movil Submarine Cable System-1 (AMX-1) stands out as the longest, extending 17,800 km and linking the United States to Brazil, Colombia, Costa Rica, the Dominican Republic, Guatemala, and Mexico. Alongside it, the Pacific Caribbean Cable System (PCCS) provides a complementary regional arc reaching Aruba, Colombia, Curaçao, Ecuador, and Panama. Together, these two systems position Jacksonville as a gateway to a broad sweep of the Western Hemisphere.

A third system, Confluence-1, is scheduled to enter service in 2026 and connects Jacksonville to other landing points within the United States, adding a domestic dimension to the port's cable portfolio.

Cables Landing at Jacksonville, FL

America Movil Submarine Cable System-1 (AMX-1) is a 17,800 km cable that entered service in 2014. From Jacksonville, it extends to Brazil, Colombia, Costa Rica, the Dominican Republic, Guatemala, and Mexico, forming one of the longer transoceanic systems in the Western Hemisphere that connects North America, the Caribbean, and South America in a single route.

Pacific Caribbean Cable System (PCCS) is a 6,163 km cable that entered service in 2015. It connects Jacksonville to Aruba, Colombia, Curaçao, Ecuador, and Panama, tracing a path through the Caribbean and down the Pacific coast of South America. Its presence alongside AMX-1 gives Jacksonville overlapping coverage of several Latin American markets.

Confluence-1 is a 2,571 km cable with a scheduled ready-for-service date of 2026. Its other endpoints are located within the United States, making it a domestic inter-landing-point system that will link Jacksonville to other U.S. cable infrastructure.

Regional Context

Within the United States, Jacksonville ranks among a broader set of Atlantic and Gulf-facing landing points. Nearby Florida peers such as Boca Raton carry eight cables each, reflecting a denser cable concentration further south along the peninsula. Jacksonville's three cables place it in the top 89% of the 167 U.S. landing points by cable count, a solid but modest position compared to high-density hubs in Florida, Puerto Rico, and the West Coast.

Network Role

Jacksonville functions as a multi-cable hub rather than a single-cable terminus, with its three systems covering two distinct roles: international connectivity to the Caribbean and Latin America via AMX-1 and PCCS, and domestic interconnection via the forthcoming Confluence-1. The two international cables together reach eight countries across the Caribbean, Central America, and South America, making Jacksonville a meaningful origination point for traffic moving between the northeastern United States and the broader Western Hemisphere.

As the United States hosts 113 submarine cables across 160 landing points, Jacksonville's three-cable profile represents a focused rather than dominant contribution to the national submarine network, yet its specific orientation toward Caribbean and Latin American endpoints gives it a distinct geographic role within the eastern U.S. cable map.
