Exa Adds Barcelona-Bilbao Route For Atlantic Cable Access

Exa Infrastructure opened a Barcelona-to-Bilbao terrestrial route that turns the Catalan capital into a direct gateway toward Atlantic and transatlantic cable systems, Capacity Media reported.

The new corridor links Mediterranean, Middle Eastern, African and Asian traffic entering Barcelona with Spain’s Atlantic coast, reducing the cross-country path for traffic bound for North America.

It also puts Zaragoza on the route, giving the Aragón data centre hub a position between Madrid, Lisbon and Barcelona-bound European flows and capacity heading back toward the Mediterranean.

Barcelona has long served Exa as an aggregation point for Mediterranean subsea systems.

The Bilbao extension changes that role by giving customers a land path from those cables into the transatlantic ecosystem instead of treating Barcelona only as a landing and exchange point.

The company operates the main eight data centres across Catalonia, and the new route gives traffic crossing Spain more than one path.

That route diversity is the operational point of the build: carriers and content platforms using subsea capacity from the Middle East, Africa and Asia can route toward Atlantic systems without depending on a single Spanish crossing.

Steve Roberts, Exa’s senior vice president of strategic investments and product management, framed the route as a way to connect Barcelona’s east-west traffic role with a shorter and more resilient path into transatlantic systems for customers and subsea cable operators.

The Bilbao link follows Exa’s addition of Dunant capacity as a fifth Atlantic option on its European backbone.

That earlier expansion tied French nodes including Paris and Bordeaux to Virginia destinations and then back into Madrid, Barcelona and Marseille.

The expansion also fits a wider European pattern in which operators are clustering cable systems around selected landing points to reduce dependency on individual transatlantic hops.

Capacity Media compared the move with MDM’s plan to combine transatlantic, Nordic and continental European routes at its Galway landing station in Ireland.

Europe’s route resilience is scheduled for discussion at Capacity Europe 2026 in October, where Roberts is due to appear on a panel about fibre and subsea networks built for the next phase of connectivity, compute and data growth.
