UniFi Cable Cat6 CMR/CMP U-Cable-C6-CMR/CMP is a Category 6 UTP (Unshielded Twisted Pair) cabling that supports speeds of up to 1Gbps. It uses 23 AWG solid copper conductor pairs and an anti-crosstalk divider, which improves pair isolation. CMP (Communications Multipurpose cable, Plenum) cabling is for use in plenum areas where air is typically circulated in a building. Cables for these areas must adhere to strict manufacturing requirements, ensuring that they can be used in these spaces.
