EXA Infrastructure Lisbon Cable Landing Station & Subsea Hub

Status: Operational / Strategic Subsea Gateway   |   Location: Greater Lisbon Digital Corridor, Portugal

Project Overview

The EXA Infrastructure Lisbon Cable Landing Station and Network Gateway is a mission-critical submarine cable landing, network interconnection and international backhaul facility operated by EXA Infrastructure in Greater Lisbon, Portugal. The site forms part of EXA's extensive European and transatlantic connectivity network, linking subsea cable infrastructure with high-capacity terrestrial fiber routes serving major digital infrastructure markets across Europe, North America and the Mediterranean region. Its strategic position within the Lisbon telecommunications ecosystem enables international carriers, network operators, cloud platforms and data center customers to access resilient routes between Portugal and major European connectivity hubs. The gateway connects subsea infrastructure associated with landing locations in Lisbon, Carcavelos and Sines with terrestrial routes extending toward important Iberian and European markets, including Madrid, Barcelona and Marseille. Designed for high availability, the infrastructure incorporates redundant power-conditioning systems, static uninterruptible power supply equipment and standby emergency generation to support continuous operation of critical telecommunications systems. Specialized cable-landing infrastructure is designed to accommodate high-capacity subsea optical transport systems, while carrier-neutral interconnection capabilities enable multiple network operators and service providers to utilize the facility. The site's importance extends beyond conventional data center infrastructure because cable landing stations provide the physical interface between international submarine networks and terrestrial telecommunications systems. As Portugal continues to strengthen its position as a gateway between Europe, Africa and transatlantic markets, the EXA Infrastructure facility contributes to the resilience and diversity of international connectivity serving the country. Its integration with EXA's broader fiber network also enables traffic to move efficiently between submarine cable systems and regional data center clusters, supporting cloud computing, enterprise connectivity, content delivery and other bandwidth-intensive digital services. The Lisbon gateway therefore represents an important component of Portugal's international digital infrastructure ecosystem.
