Abstract: A device may receive, from a fiber sensor device, sensing data associated with a fiber optic cable, the sensing data being produced by an activity that poses a threat of damage to the fiber optic cable, and the sensing data identifying: amplitudes of vibration signals, frequencies of the vibration signals, patterns of the vibration signals, times associated with the vibration signals, and locations along the fiber optic cable associated with the vibration signals. The device may process, with a machine learning model, the sensing data to determine a threat level of the activity to the fiber optic cable, the machine learning model having been trained based on historical information regarding detected vibrations, historical information regarding sources of the detected vibrations, and historical information regarding threat levels to the fiber optic cable. The device may perform one or more actions based on the threat level to the fiber optic cable.

Abstract: A device may receive, from a sensor device, cable distance data identifying cable distances along a fiber cable to vibrations experienced by the fiber cable, and may receive location data identifying locations associated with the vibrations. The device may correlate the cable distance data and the location data to generate correlated location data, and may store the correlated location data in a data structure. The device may receive, from the sensor device, data identifying a cable distance along the fiber cable to an alarm condition associated with the fiber cable, and may determine a location of the alarm condition based on the correlated location data and the data identifying the cable distance along the fiber cable to the alarm condition. The device may perform actions based on the alarm location.
