Project Overview
The Fibre Optic Corridor between Portugal and Spain (FOCPS) is an EU co-funded project under the Connecting Europe Facility (CEF Digital) programme, implemented by lyntia, to strengthen cross-border connectivity through a strategic, high-capacity and redundant fibre-optic route. It deploys an alternative terrestrial corridor supporting growing data traffic, enhancing competition and aligning with EU goals for resilient and integrated digital infrastructures.

Contribution to European Connectivity
FOCPS contributes to strengthening international connectivity across
the Iberian Peninsula by developing an additional cross-border fiber
infrastructure corridor between Portugal and Spain.
The project increases network diversity, improves connectivity
resilience and supports the development of the European digital
infrastructure ecosystem.
01
Infrastructure Resilience
New physical infrastructure independent of existing routes, reducing systemic vulnerability for operators and end users across the Iberian Peninsula.
02
Route Diversity
An additional cross-border corridor diversifies the physical paths available for data transport between Portugal, Spain and the wider European network.
03
Cross-Border Connectivity
New colocation and shelter points create access opportunities for operators, supporting the growth of interconnection across Southern Europe.
Interconnection Ecosystem
The infrastructure developed within the FOCPS project enhances connectivity between telecommunications operators, digital infrastructure providers and data transport networks across Portugal and Spain.
The corridor is designed to serve as a wholesale infrastructure layer,
open to telecommunications operators seeking diversified routing between
the two countries.
Cross-border data transport infrastructure
Accessible to telecommunications operators in Portugal and Spain
High-capacity optical transport capability
Colocation and shelter points distributed along the corridor
Route diversity enabling flexible connectivity architectures
