The defense zone type layer twisted vibration sensing optical cable uses polyethylene sheath, coated steel strip, and reinforced steel wire to protect the optical fiber. The optical fiber has excellent mechanical properties such as compressive and tensile properties that can be directly buried, making it an ideal detection unit for distributed vibration optical fiber sensing. It is widely used for intrusion monitoring in airports, power plants, chemical enterprises, border security, prisons, oil pipelines, and various key areas.
