How we bring our customers to the DB network

We start with the inquiry

Simply let us know the start and end points of your desired route along the rail, then we will check the availability. If we can offer you free capacities, you will receive a non-binding offer from us.

Then it goes into the realization

Once the contract has been signed, we start the realization process. For do so, we create a handover point at the DB property line at the start and end point of your desired route. The respective handover point is builtaccording to your needs.

At the end follows the operation

After the successful implementation of the handover points, the Dark Fibre will be available to you on the leased section for your needs. While you continue to expand your network starting from the handover points, we ensure trouble-free availability of your Dark Fibre route along the rails.
