What is a vibrating optical cable? What are the advantages and disadvantages compared with traditional electronic fence and infrared correlation?

Isn't vibrating optical cable a device that sends out alarm signals by sensing the vibration of optical cable? There is a Jing 'anmeng product in Beijing that is ok.

Vibration optical fiber cable takes high-sensitivity vibration sensing optical fiber cable as detection sensor to realize intelligent detection and early warning, intrusion alarm, system linkage and other functions.

Advantages: A new generation of perimeter prevention system with high reliability, no blind area, zero missing report, low false alarm and no restriction of environmental and geographical conditions. The system adopts advanced distributed optical fiber interference sensing principle, which can be applied to real estate, electric power, army, airport, petrochemical, national defense, justice, government, culture and other fields. Disturbance-free key, long transmission distance.
