cable categories

Following are the categories for telephone and network cables, which are typically abbreviated "Cat." For HDMI video cables, see HDMI cable types.

Cat 1 and Cat 2 are unofficial voice grade standards, while Cat 3 to 7 are based on the EIA/TIA-568-B standards. Most wiring for local networks that support Gigabit Ethernet is Cat 5e, an improved version of Cat 5. Cat 8 is for short distances in datacenters. See twisted pair.
