Abstract
The present invention provides an optical cable monitoring device and optical cable monitoring method that can accurately identify abnormal locations in optical cables without being affected by the installation environment. [Solution] An optical cable monitoring device comprising: a vibration application unit that applies vibration to the optical cable at a vibration application position located in the monitored section of the optical cable; a vibration waveform acquisition unit that acquires the vibration waveform of the monitored section of the optical cable at a vibration waveform acquisition position different from the vibration application position located in the monitored section of the optical cable; a corrected vibration waveform acquisition unit that acquires a corrected vibration waveform obtained by correcting the vibration waveform in the monitored section of the optical cable; and an abnormal location acquisition unit that acquires abnormal locations in the monitored section of the optical cable based on the corrected vibration waveform.
