Telehouse environment

The KleyReX locations are operated within professional carrier-class co-locations. We differentiate between "KleyReX sites" and "KleyReX accessible sites". KleyReX site are fully equiped sites with KleyReX switching infrastructure. At KleyReX accessible sites all participants will be transported to the next KleyReX site via fiberglass connection.


The KleyReX network is a setup of Foundry and Cisco switched infrastructure. All sites are connected through rented fiberlines equiped with Cube Optics CWDM systems for link aggregation on different wavelength. Participants can be connected with interface speeds from 100 Mbit/s up to multiple Gbit/s. Inhouse connections to KleyReX infrastructure will either be done with copper (CAT 5,6,7) or fiber connects (singlemode/multimode).

Accommodation of router systems

For accommodation of routers, servers, switches, converters participants can rent space at the co-location companies from a single unit up to full racks, suites or own rooms. Feel free to ask us about helpfull information on the different possibilities.


Access to KleyReX is only possible to authorised persons. You can access your equipment with advance notice around the clock together with authorised personnel. For all communication and operations we run a 24/7 NOC and hotline service.
