(1. The network cable problem causes the network speed to slow down. We know that the twisted pair is composed of four pairs of wires that are tightly twisted together according to strict rules to reduce the impact of crosstalk and background noise. At the same time, in the T568A specification and the T568B specification, only four wires 1, 2 and 3, 6 of the twisted pair are used, among which, 1, 2 are used for transmission, 3, 6 are used for reception, and 1, 2 must come from a Winding pair, 3 and 6 must come from a winding pair. Only in this way can crosstalk be prevented to the maximum extent and data transmission can be ensured. Network cables that are not made according to the correct specifications (T586A, T586B) are in great danger.)
