Availability down to the last fibre: We help you utilise your dark fibre network.

We’ve been operating dark fibre networks throughout Germany since as far back as 1997, as part of which we have activated more than 140,000 km of these fibre-optic cables for our customers. Make use of our fibre-optic infrastructure and the complete range of services to go with it. 

Our fibre-optic Maintenance Management Centre (MMC) is there to help you with your enquiry and with all planning, consultancy, realisation, maintenance and servicing work you may require. OGE’s nationwide maintenance organisation ensures the quality and availability of your fibre-optic network around the clock. The MMC will provide all the services you need – right down to geographic and technical documentation.

The processes and IT installations required for the operation, expansion and administration of the cable infrastructure and system equipment sites are managed centrally by us.
