Monoprice™ 23AWG Cat6A 550MHz UTP Solid, Plenum-Rated (CMP) Bulk Pure Bare Copper Ethernet Cable is premium, high-speed cabling designed for use in 10GBase-T (10Gbps) network environments. Constructed using 23AWG solid, pure bare copper conductors with a CMP-rated PVC jacket, it exceeds TIA/EIA 568-C.2 standards and is safe for use in the Plenum spaces of commercial class buildings. This cable is UL-listed and RoHS compliant. Monoprice Ethernet cables are made of 100% pure bare copper wire, as opposed to copper clad aluminum (CCA) wire, and are therefore fully compliant with UL® Code 444 and National Electrical Code® TIA-568-C.2 fire and safety standards, which require pure bare copper wire in communications cables.
