ALBA-1

Overview

ALBA-1 is an active submarine cable system traversing the Caribbean Sea, connecting landing points at La Guaira in Venezuela, Siboney in Cuba, and Ocho Rios in Jamaica. The system is owned and operated by Telefónica, the Spanish telecommunications group with deep roots across Latin America and the Caribbean.

Route and Significance

The cable's routing reflects both geography and politics. Cuba sits in a peculiar position among Caribbean nations: despite its location in one of the world's most cable-dense regions, it has historically had very limited access to international fibre-optic infrastructure. ALBA-1 addresses that directly, with the Siboney landing station on Cuba's southeastern coast providing the island with a dedicated submarine fibre link.

La Guaira, Venezuela's principal cable landing gateway serving Caracas, anchors the southern end of the system. Ocho Rios on Jamaica's north coast serves as the third node, connecting the system into Jamaica's broader telecommunications infrastructure and providing onward routing options into the wider Caribbean and Atlantic cable network.

Ownership and Build Context

Telefónica is the sole documented owner of ALBA-1. The company's existing network footprint across Latin America made it a logical operator for a cable serving this corridor. Details on the system's builder, ready-for-service date, length and design capacity are not publicly documented.

Regional Context

The Caribbean basin is crossed by numerous cable systems, most of which bypass Cuba entirely. ALBA-1 is therefore among a small number of systems that directly serve the Cuban market, giving the route an outsized strategic importance relative to what its physical specifications alone might suggest. For Telefónica, the system represents an extension of its regional infrastructure ambitions into one of the Caribbean's most isolated telecommunications markets.
