Cat6 cables are designed for operating frequencies up to 250 MHz. They are used for signal transmission with high data transfer rates (1 Gbps). Due to the high signal frequencies, careful handling is required during installation and assembly, especially at the connection points of the wires. The individual wire pairs in Cat6 are twisted with varying tightness, which reduces susceptibility to interference even more than in Cat5e. Application areas for Cat-6 cables include voice and data transmission, as well as multimedia and ATM networks. Even more powerful are cables according to Cat6e (500 MHz) and Cat6a (625 MHz).
