Dedicated cable


At Reintel, we offer a dedicated cable solution designed to provide capillarity and access to our customers’ backbone or metropolitan transport networks.

At our customer’s request, with this dedicated cable we can deploy specific dark fibre sections within the railway environment, on the conventional long distance or on the commuter railway networks. These sections also connect Points Of Interconnection (POIs) of one or more customers, in order to complete the access to their backbone networks.

Our Points Of Interconnection can be located at the telecommunications co-location centres or be custom-built to meet our customer’s needs.




We succeed in making available to our customers the highest degree of capillarity in provincial capitals and on the outskirts, by using dedicated cable and alternatively, metropolitan rings.


Customised deployment

We design custom-built routes for our customers using dedicated cable in the railway network, and we make available Points Of Interconnection (POIs) in order to connect to the existing POIs.



Our customers’ dedicated cable demand allows Reintel to grow steadily and expand its dark fibre network.


Service level

The dedicated cable product ensures a top-level service for our customers, which is basic for their communications networks management.



We market our backbone network by fibre pair cables between Points Of Interconnection, either by a transfer of right to use or by a multi-year period lease.



With this product and by means of our telecommunications co-location centres, we can enable interconnections between various customers.

Dedicated cable in big cities: the metropolitan rings

At Reintel we have a specific solution for capillarity in provincial capitals: the metropolitan rings. These are redundant solutions of dedicated long-distance cable that provide connectivity in the metropolitan areas of the major Spanish cities.

Our metropolitan rings, comprised of a minimum number of one fibre pair cable, are installed parallel to the commuter railway line. From these locations, they interconnect with our customer’s network through the Points Of Interconnection and the telecommunications co-location centres, thus enabling their network to enter the cities.

A network of more than 52,000 km throughout Spain


Red Eléctrica Infraestructuras de Telecomunicación (Reintel) is the subsidiary of the Redeia that, as of 1 July 2015, has been responsible for the management of the Company’s telecommunication business, an activity that previously, from 2008, had been carried out by Red Eléctrica Internacional. Reintel focuses on the commercial exploitation of dark fibre infrastructure and technical facilities connected to such infrastructure relying on an optical fibre network of more than 52,000 km. Therefore, we have the full support of a solid and solvent business group with a vast experience in the telco market since 1997.

At Reintel we manage two networks, each one with its own history and unique technical features: the unused, surplus fibre network of Red Eléctrica and, since November 20, 2014, the surplus marketable fibre network of ADIF.

These are two networks that are deployed through different infrastructures, each with different requirements and constraints, but which are being interconnected by Reintel at many points in order to offer services to our customers as if we were dealing with a single network by using the best of both. At Reintel we are working to provide our customers with a single network framework in which other networks integrate and interconnect every day.

At Reintel we are aware of how important for our customers is to have detailed information about our infrastructure and, therefore, in the Infrastructure section on this web we present both the technical features of the sites and the details of the network map displayed by province.

We invite you to discover, in the Infrastructure section on the web, detailed information about our dark fibre network (currently more than 52,000 km) and the 1,344 sites (810 on the electricity grid and 534 on the railway network) that we make available to you.
