Monoprice Cat8 Ethernet Network Cables are the first to bring up to 40Gbps transfer speeds and up to 2GHz bandwidth using copper conductors and RJ45 connectors. Available in two colors and twelve lengths, ranging from 6 inches to 30 feet. Monoprice Cat8 Ethernet Cables is the ideal future-proof, cost-effective, and high-performance solution IT managers and data center operators have been looking for. 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.
