crossconnects

A crossconnect is a direct, private connection between two networks or endpoints that is established within the same physical facility, such as a data center, colocation campus, or telecom exchange. The link typically uses fiber or copper media and is designed to bypass public networks in order to deliver lower latency, higher security, and more predictable bandwidth. Crossconnects are provisioned as a dedicated path between approved ports or service demarcations and are often managed through a facility’s internal cabling infrastructure.

In data centers and colocation facilities, crossconnects connect a customer’s equipment to a service provider, to another customer, or to a network point of presence within the same building or campus. They are implemented using crossconnect cabinets, patch panels, or wall boxes, with technicians performing the physical patching between designated ports. Service agreements specify factors such as port speed, total bandwidth, and the access and provisioning processes. Crossconnects enable direct interconnections without traversing external networks, contributing to improved performance and security for connected parties.

In telecom and carrier environments, the term can refer to cross-connect distribution frames or similar patching infrastructure that interconnects circuits between carriers and customers. These facilities facilitate inter-carrier and customer interconnections in carrier hotels and central offices, supporting services such as leased lines, internet access, and local connectivity.

Advantages of crossconnects include low latency, deterministic performance, enhanced security, and easier fault isolation. Considerations include ongoing costs for space and port usage, physical access requirements, and the need for proper governance and change management to manage connections.
