Category 8 (Cat 8)

A twisted-pair cable standard for 40 Gigabit Ethernet and other interconnections that is backward-compatible with Cat 5e, Cat 6, and Cat 6A cable (part of the EIA/TIA 568A standard). Cat 8 features a shield around each twisted-pair and a further shield enclosing all twisted-pairs. It is only specified at 40Gbps for runs up to 30m (100ft).
