Making sure data arrives safely. When transmitted over long distances, data can run out of steam. To prevent this from happening, we use repeaters. Repeaters, which strengthen or retransmit optical signals, are installed roughly every 80 km along the route, ensuring that the signal is just as strong when data reaches its destination as it was at the start. In a pilot project, we have tested the solution in detail with one of our customers in order to be able to provide you with an ideal standard. As a result, the repeater solution is now a fixed component of our dark fiber offering.

With our Rail Connectivity Master Plan, we are working with DB to implement the coverage requirements for mobile communications companies. We're equipping rail infrastructure and trains for 5G, and public mobile operators are taking care of the network coverage along railway lines, including in tunnels. This means that all DB passengers will be able to enjoy uninterrupted phone calls and stable internet access.
