Cutting-edge technology, 24/7 monitoring, and a wealth of experience: We apply our know-how to enhance your project

With almost 30 years of experience in leasing fiber-optic capacity, we are your reliable and efficient partner in the process of building your individual data network. Through our cooperations with a large number of other network operators, we are able to configure nearly any network structure – not only in Germany but also in other European countries.


We now have a fixed portfolio of around 8,500 km of fiber-optic cabling available for leasing. And if there are any coverage gaps, we lease the missing sections, making it a one-stop shop for you.

We work at the cutting edge of technology, with staff monitoring it 24/7 from Kassel as well as from the air by conducting regular helicopter flights along the pipeline.
Apart from leasing capacity of our fiber-optic cables (dark fiber), we also offer broadband connections to develop rural regions close to the pipelines.
