A cross connect is a physical connection that links two pieces of computing equipment together within the same data center or colocation facility. Cross connects are typically used to establish a direct, dedicated, high-speed connection between devices or service provider networks. Servers, switches, routers are most commonly connected devices. Connections can be made using different types of cabling, such as fiber optic or copper, with SMF, MMF, and Cat 5/6 cabling the most common. The physical connection may be made using patch panels, jacks, or other types of connectors. A Cross Connect is also known as a Cross Connection or Network Interconnection.
