About us
We are the largest neutral operator of fibre optic infrastructure in Spain

Red Eléctrica Infraestructuras de Telecomunicación (Reintel), a subsidiary company wholly owned by the Red Eléctrica Group, operates as a neutral telecommunications infrastructure provider. Our core business is operating telecommunications infrastructure focusing mainly on the lease of dark fibre and sites to our clients.
We currently have an optical fibre network comprising more than 50,000 km of cable deployed along the electricity transmission grid and the railway network. This allows us to ensure all telco players a transparent and equal access to the network.
Additionally, we provide maintenance services for Red Eléctrica's own fibre optic cables and telecommunications equipment.
Our origins
Our experience in the telecommunications sector dates back to 1997. From then on we have been a primary provider for the key sectoral players operating in Spain. Our priority is operational excellence focused on ensuring our clients with the highest levels of service quality and availability.
