PBT Tube Protected Fiber Optic Sensing Cable

The PBT tube protected fiber optic sensing cable is comprised of the fiber, oil, PBT tubing, aramid yarn, and a sheath that can be made from different materials including LSZH, PVC, PE, and PU. Due to this structure, the optical cable for sensors comes with a high tensile strength, is lightweight and is resistant to water and oil.

This sensing fiber optic cable is ideal for use in subway systems, tunnels, and fire protection industries to sense temperature and pressure, making it ideal to prevent disasters and accidents.

Features of the Fiber Optic Sensing Cable
1. Its nonmetallic structure ensure the distributed temperature sensing system has a great transmission and environmental performance.
2. Protected by PBT tubing, the sensing cable is lightweight, has a small diameter, a high density and features an excellent waterproof performance.
3. The sealing design makes it environmentally friendly, flame resistant, and blocks water and oil.
