Claim 0:
1. A method, comprising:
providing, by a device and to a fiber sensor device, a request for sensing data associated with a fiber optic cable,
the request including a schedule according to which the fiber sensor device is to transmit the sensing data;

receiving, by the device, from the fiber sensor device, and based on the schedule, the sensing data,
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;

processing, by the device and 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; and

performing, by the device, one or more actions based on the threat level to the fiber optic cable.
