| Zusammenfassung: | To provide a monitoring device capable of specifying an abnormality occurrence point without requiring much time, the monitoring device is provided with a reception means 1 for acquiring information about variation of the optical power level of a control signal transmitted to a transmission path and a monitoring means 2, when the variation of the optical power level of the control signal does not satisfy a prescribed condition, for monitoring the transmission path on the basis of back-scattered light of an optical pulse outputted to the transmission path. |
