The transmission frequency of the six types of wires is 1MHz ~ 250MHz, and the comprehensive attenuation crosstalk ratio (ps-acr) of the six types of wiring systems should have a large allowance at 200MHz. It provides twice the bandwidth of the five types of wires, which are 100M, 155M and 200M respectively. In the short distance transmission of five categories, super five categories, six categories can achieve 1Gbps, six cabling transmission performance is higher than five categories, super five standards, the most suitable for the application of transmission rate higher than 1Gbps.
