Super class line: It has the characteristics of low crosstalk and low attenuation. It increases the test requirements of near-end crosstalk power and summation compared with the five kinds of lines, and has a higher attenuation crosstalk ratio and smaller delay error. The performance is better than that of the five kinds of lines. It is said that it has been greatly improved, and the maximum transmission rate is 1000Mbps data transmission, which is the lowest entry threshold in quasi-gigabit Ethernet.http://www.hylink-cables.com/hdmi-cable/
