Abstract: An optical line monitoring device includes an OTDR for selectively transmitting monitoring light by an optical line for connecting a supplier-side terminal with an ONT and receiving monitoring light reflected by the optical line and an analysis unit for analyzing a trace of the monitoring light, wherein the analysis unit sets two or more types of reflection peak factor threshold values in a OTDR reference trace of the monitoring light, measures two or more types of reflection peak factors corresponding to the reflection peak factor threshold values in the OTDR reference trace of the monitoring light, compares values of the measured reflection peak factors with the set reflection peak factor threshold value, and determines a reflection peak in the OTDR reference trace of the monitoring light; the analysis unit measures two or more types of reflection peak factors in a measured trace of the monitoring light, compares the measured reflection peak factors with the set reflection peak factor threshold values, and determines a reflection peak in the measured trace of the monitoring light; and the analysis unit compares a reflection peak factor of the reflection peak of the measured trace with a reflection peak factor of the reflection peak of the OTDR reference trace and determines whether a fault has occurred in the optical line.
