Category 6 network cables can run at 500 Mbps.
Category 6 cabling has a transmission frequency range of 1 MHz to 250 MHz. The combined attenuation-to-crosstalk ratio (PS-ACR) of a Category 6 cabling system at 200 MHz should have a large margin. It provides twice the bandwidth of Category 5 cabling: Category 5 offers 100 Mbps, Category 5e offers 155 Mbps, and Category 6 offers 200 Mbps. For short-distance transmission, Category 5, Category 5e, and Category 6 cabling can all reach 1 Gbps. Category 6 cabling offers higher transmission performance than Category 5 and Category 5e standards, making it ideal for applications with transmission rates exceeding 1 Gbps.
