The common network cable grades are divided from low to high according to transmission performance, with core differences in network speed, bandwidth, and anti-interference ability: Cat5e: a cost-effective choice, supporting 1Gbps network speed, 100MHz bandwidth, and better anti-interference ability than Cat5, preferred for home and ordinary office use. Cat6: Performance upgrade, supporting 1Gbps (up to 55 meters) or 10Gbps (up to 5 meters), bandwidth of 250MHz, with an internal cross skeleton to reduce interference, suitable for high-definition audio and video, e-sports and other scenarios with high network speed requirements. Кат6а: Enhanced version of Cat6, supporting 10Gbps network speed (up to 100 meters), bandwidth of 500MHz, stronger anti-interference ability, suitable for enterprise computer rooms, large apartments, and whole house high-speed networking. Кат. 8 is a high-end Ethernet cable that has been recognized by mainstream standards, is compatible with RJ45 interfaces, supports 25G-40Gbps ultra high speed short-range transmission, and is designed specifically for data centers and other scenarios.
