Our origins

Our experience in the telecommunications market began in 1997 and, since then, we have been a benchmark provider for the main players in the sector with a presence in Spain. Our priority is excellence in operations to guarantee our customers high levels of service quality and availability.

What we do

We offer the largest and the best quality dark fibre network.

Reintel’s business goes beyond offering optical fibre infrastructure. Our mission takes us one step further. We provide a meshed and redundant optical fibre network which is connected to the insular systems and internationally accessible. Not only do we operate and manage our extensive optical fibre backbone network, but we also provide sites and technical spaces for electronic equipment housing.
At Reintel we devote every effort to provide our clients with customised solutions while working alongside with them supporting their growth and development process. We know every customer is unique and that is why we ensure transparent and neutral access to our infrastructure network. Our network is adapted to our customers’ needs. We are also aware of how important the proper operation of both the backbone network and the services related to the sites is for our customers. Therefore, we provide them with high-level service quality and availability.
To this end, in order to attain the target of providing the largest and the best optical fibre network available, we are committed to continuous investment and innovation. We are constantly investing in deploying new infrastructure as well as in renovating and improving our existing facilities.

How we do it

We prioritise operational excellence and to do this we count on the best professionals to ensure quality and availability.

Our cornerstone is to prioritise excellence both in the operations and in the corrective and preventive maintenance processes on our infrastructures. We apply the best managing and operational practices on our infrastructures in order to provide a reliable and quality service.
Additionally, we are available 24 hours a day, 365 days a year through our permanent Network Operations Centre. Our aim is ensuring that our customers are assisted promptly, thus ensuring top-quality service.
Each of our services counts on a highly specialised team committed to each project and devoted to the task of seeking and proposing customised solutions.
Our target is building long-term relationships with our customers in order to take part in their growth and development process.
