Save the time and hassle of building Ethernet cables by using fixed-length STP Cat6A Ethernet network cables from Monoprice! 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.
