When preset detection conditions are met, an ONU collection to be detected is confirm in a passive optical network (PON). The ONU collection to be detected comprises at least one ONU, and a decision procedure of the ONU in the ONU collection is carried out. The effective time that all the ONU in the ONU collection to be detected continuously outputs light indication signals under the preset conditions is counted, and in other words, the time that optical output power is not zero is counted. When the effective time that the light indication signal is output or the time that the optical output power is not zero does not meet a first preset statistics condition, the condition that the rascal ONU exists in the ONU collection to be detected is judged. By utilization of the detection method of the rascal ONU, the rascal ONU can be timely detected whether to exist in the PON or not. When the rascal ONU is found to exist in the system, the isolation of the rascal ONU is carried out. Therefore, the problem that due to the fact that the rascal ONU exists in the system and flashes in an incorrect authorization gap, data collision occurs is avoided.
