About us

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


Reintel was founded in 1997 and is today the largest dark fibre optic operator in Spain and one of the leading players in the field of telecommunications nationwide.

It manages a network of more than 52,200 km of cable deployed over the transmission grid of the electricity system and the railway network. Its main activity is the leasing of dark fibre as well as sites and technical spaces for housing electronic telecommunications equipment.

Today, Reintel is the cornerstone for the deployment of networks and, therefore, its role is paramount in providing a new generation of connectivity that is both universal and inclusive.
