All connections to DE-CIX require a single-mode private interconnect (a.k.a. cross connect or in-house cabling). A cross connect is a dark fiber point-to-point interconnection. They are used to access the DE-CIX platform.
You can order cross connects via DE-CIX in Frankfurt, Hamburg, Munich, and Dusseldorf. In select enabled sites in Frankfurt, customers can order cross connects to interconnect networks directly.
At the other platforms, DE-CIX will provide all customers with demarcation details in the appropriate data center. Please talk to your data center operator for details.
