Tocopilla, Chile: Submarine Cable Landing Point

Tocopilla is a city and commune located in the Antofagasta Region in northern Chile, where it serves as the capital of the province bearing its name. Situated along Chile's Pacific coastline, Tocopilla is home to one submarine cable landing, connecting it to Chile's broader coastal infrastructure network. That cable, Prat, is a domestic Chilean system, establishing Tocopilla as a node within an intra-national submarine cable corridor rather than an intercontinental one.

The Prat cable, with a length of approximately 3,500 kilometres, links multiple points along the Chilean coast, making Tocopilla one of several Chilean cities served by this system. The cable reached ready-for-service status in 2020, placing Tocopilla's submarine cable history firmly in the modern era of Chile's coastal connectivity development.

Cables Landing at Tocopilla

The Prat cable is the sole submarine cable landing at Tocopilla. Spanning approximately 3,500 kilometres and entering service in 2020, Prat is an entirely domestic Chilean cable, with all its endpoints located within Chile. This makes it a coastal inter-city system designed to connect communities along the Chilean Pacific seaboard. Tocopilla's position in northern Chile places it as one of the intermediary or terminal points along this route, contributing to a chain of Chilean landing points served by the same cable.

Regional Context

Within Chile's submarine cable landscape, which includes 14 landing points spread across the country, Tocopilla shares its single-cable status with Antofagasta, Caldera, Cartagena, and Constitución. Larger hubs such as Valparaíso, which hosts five cables, and Arica, which hosts three, represent more densely connected points in the national network. Tocopilla ranks within the lower tier of Chilean landing points by cable count, alongside several peers that similarly serve as single-cable termini.

Network Role

Tocopilla functions as a single-cable landing point within a domestic Chilean submarine network. Its connection through the Prat cable enables coastal data transmission along Chile's extended Pacific shoreline, linking it to other Chilean cities rather than to international destinations. As a terminus or waypoint on an intra-national system, Tocopilla contributes to the distribution of submarine cable capacity within northern Chile, a region that also includes the nearby single-cable landing point of Antofagasta.

Within Chile's submarine cable graph, Tocopilla represents one of several modestly connected nodes that collectively extend domestic cable coverage northward along the coast, ensuring that communities in the Antofagasta Region are included in the country's submarine cable infrastructure alongside the more internationally connected hubs further south.
