Cat 6 is the sixth generation of twisted pair Ethernet cabling that is used in home and business networks. Cat 6 cabling is backward compatible with the Cat 5 and Cat 5e standards that preceded it.

The ends of a Cat 6 cable use the same RJ-45 standard connector as previous generations of Ethernet cables.

The cable is identified as Cat 6 by printed text along the insulation sheath.

An enhanced version of Cat 6, called Cat 6a, supports up to 10 Gbps speeds.
