1. Delay deviation (Skew):The difference in the length of different line pairs in the same cable leads to a difference in the time it takes for the signal to reach the end point in different line pairs in the cable, and the maximum difference is the delay deviation.2. Near-end Crosstalk (Next):In a string loop, the crosstalk received at the same end of the signal source in the main string loop is called nea
