Monoprice Entegrade Cat8.2 PoE+ Networking Cables (40G speed) provides flexibility for cabling projects and PoE applications. The high performance transmission of Cat8.2 cables featuring IEEE 802.3at (PoE+) support is designed for data centers. Monoprice Ethernet cables are made of 100 percent 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.
