Crimping RJ45 Patch cable (T568B)

Category 6 cable can be identified by the printing on the side of the cable sheath.<ref>Ethernet Cable Identification and Use</ref>

Cat 6 patch cables are normally terminated in 8P8C modular connectors. If Cat 6 rated patch cables, jacks, and connectors are not used with Cat 6 wiring, overall performance is degraded to that of the cable or connector.

Connectors use either T568A or T568B pin assignments; although performance is comparable provided both ends of a cable are the same, T568B is a deprecated standard and no longer supported by TIA.
