cable categories

Following are the categories for telephone and network cables. HDMI audio/video cables also use category designations (see HDMI).

Categories 1 and 2 are unofficial standards, while Categories 3 to 7 are based on the EIA/TIA-568-B standards. Most new wiring for LANs is CAT5e, an improved version of CAT5. See twisted pair.
