The CAT-8.1 system allows for high data rates of up to 40 GBit/s without the need to switch to fiber optics. Combined with installation cables and RJ45 connectors of the CAT-8.1 standard, the patch cable can be integrated into a high-quality high-speed data link. The 20-meter LAN cable supports 25GBase-T and 40GBase-T Ethernet networks, is capable of 40 gigabits, and is backward compatible with 10BASE-T, 100BASE-TX, and 1000BASE-T. With a transmission bandwidth of up to 2,000 MHz, this Ethernet cable has four times the bandwidth of CAT-6A cables. It features S/FTP overall shielding: aluminum foil shielding for individual pairs of wires (PiMF) and aluminum braid shielding for the cable jacket. Both ends are equipped with RJ45 connectors 8P8C with 50 μm gold-plated contact surfaces and locking protection. The CAT-8 LAN cable is suitable for Power over Ethernet (PoE), PoE+, UPoE, 4PPoE, and HDBaseT. It has a low-smoke and halogen-free LSZH cable jacket.
