<p>Disclosed are a passive intermodulation position detection method and device. The method comprises: transmitting a passive intermodulation test signal and collecting a passive intermodulation signal; and, determining a correlation between the size of a passive intermodulation and the position thereof on the basis of a time relation between the passive intermodulation signal and the passive intermodulation test signal. By means of the technical solution of the present invention, fault maintenance and detection costs are reduced, the speed of delivery is increased, the efficiency of fault diagnosis is increased, self-diagnose function of the device is implemented, and network quality and customer satisfaction are increased.</p> |
