(Common faults of wiring system and their location technology----In the acceptance process of integrated wiring project, the acceptance test of wiring system performance is a very important part. The physical performance and electrical performance of the link under test are tested. Through testing, you can find various faults in the link, including wiring diagram (WireMap) error, cable length (Length) problem, excessive attenuation (Attenuation), near-end crosstalk (NEXT) too high, return loss (ReturnLoss) is too high. In order to ensure that the project quality passes the acceptance, it is necessary to determine and solve the fault in time, which puts forward higher requirements on the fault location technology and the location accuracy.)
