Cat 7, is a cable standard for Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional Cat 5 and Cat 6 Ethernet cable. Cat 7 features even more stringent specifications for crosstalk and system noise than Cat 6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole.

The Cat 7 cable standard has been created to allow 10-gigabit Ethernet over 100 meters of copper cabling. The cable contains four twisted copper wire pairs, just like the earlier standards. Cat 7 can be terminated either with RJ-45 compatible GG45 electrical connectors which incorporate the RJ-45 standard or with TERA connectors. When combined with GG-45 connectors, Cat 7 cable is rated for transmission frequencies of up to 600 MHz. When combined with TERA connectors, Cat 7 cable is rated for transmission frequencies above 600 MHz.
