The invisible infrastructure of global connectivity

The Tannat submarine cable is a South Atlantic cable system that connects South America directly with Europe, making it one of the most important data routes between the two continents. Named after the Tannat grapevine, which is cultivated in both Uruguay and France, the cable symbolizes the close economic and cultural ties between South America and Europe. Submarine cables such as Tannat form the invisible foundation of global data traffic, as over 99% of international data flows through them rather than through satellites or the cloud.

Route & connection

Tannat connects Las Toninas (Argentina) and Maldonado (Uruguay) with Marseille (France) and bridges the South Atlantic on a route that links South America directly with the European Mediterranean region. This routing makes Tannat a strategically valuable cable for companies with locations in Argentina and Uruguay that require a direct and latency-optimized connection to Europe. With a total length of around 11,700 kilometers, Tannat is one of the longest direct connections between South America and Europe.
