Iquique, Chile: Submarine Cable Landing Point

Iquique is a port city on the Pacific coast of northern Chile, serving as the capital of both the Iquique Province and the Tarapacá Region. Situated west of the Pampa del Tamarugal on the edge of the Atacama Desert, the city occupies a stretch of coastline that connects it to Chile's broader submarine cable network. One submarine cable currently lands at Iquique, linking the city to the national undersea communications infrastructure.

The single cable serving Iquique is the Prat system, a domestic cable that connects multiple points along the Chilean coast. Its presence positions Iquique as a node within a Chile-only corridor, enabling connectivity between coastal communities along one of the world's longest and most geographically isolated shorelines.

Cables Landing at Iquique

The Prat cable is the sole submarine cable landing at Iquique. Spanning approximately 3,500 kilometres, it reached its ready-for-service status in 2020 and remains in draft status. The cable connects landing points exclusively within Chile, making it a domestic system designed to serve the country's extended Pacific coastline rather than providing international or intercontinental links. Its considerable length reflects the geographic challenge of connecting Chile's far-flung coastal communities along the narrow strip of land between the Andes and the Pacific Ocean.

Regional Context

Within Chile's submarine cable landscape, which spans 14 landing points, Iquique ranks alongside a small group of single-cable landing points that includes Antofagasta, Caldera, Cartagena, and Constitución. The most connected landing point in the country is Valparaíso, served by five cables, while Arica - the nearest major city north of Iquique along the same coastline - hosts three cables. Iquique's single-cable configuration places it in the lower tier of Chilean landing points by cable count, though its position in the northern coastal corridor gives it a role distinct from more southerly nodes.

Network Role

Iquique functions as a single-cable terminus within a domestic Chilean submarine corridor. The Prat cable, at 3,500 kilometres, provides coastal connectivity along Chile's Pacific shoreline, and Iquique's inclusion on the system extends that reach into the Tarapacá Region of the far north. As a terminus rather than a multi-cable hub, the landing point does not offer route diversity or international onward connectivity through its submarine infrastructure.

In the wider Chilean submarine cable graph, Iquique represents one of several northern coastal nodes that together help distribute domestic connectivity across a country whose geography makes terrestrial alternatives along the coast both difficult and expensive. Its presence on the Prat system ensures that one of Chile's major northern port cities remains connected to the national undersea network.
