Cat8 is recommended for data-center environments or high-speed switch-to-switch and server communications in a 25 Gbps or 40 Gbps copper network. Cat8 is the best choice unless you want to install a fiber network, too. Due to the design, Cat8, Cat8.1 and Cat8.2 support transmission speeds of 10 Gbps up to 100 meters (328 feet) or 25 Gbps and 40 Gbps up to 30 meters (98.5 feet) with an impressive 2,000 MHz frequency that even better prevents crosstalk. Where Cat8 and 8.1 are backward compatible, Cat8.2 is not since it does not use standard RJ45 connectors.
