1. Multimode optical fiber is used for temperature leakage monitoring.

2. Small outer diameter, simple structure, fast thermal penetration, and fast temperature response.

3. The optical cable is armored with spiral steel pipes and protected by a single layer of twisted stainless steel wire, which provides excellent impact resistance and tensile strength.

4. PE outer sheath is used to make the optical cable have anti-aging, corrosion resistance, waterproof, abrasion resistance and other properties.

5. Fiber optic cables have high mechanical strength and are suitable for burial and overhead.
