Armored Fiber Optic Cable for Temperature Sensing

The armored fiber optic cable is a general sensor cable used for distributed temperature sensing (DTS) systems. This DTS cable is suitable for the vast majority of DTS environments and is designed with a high intensity armor that features excellent mechanical properties such as tensile strength and crush resistance.

This type of armored fiber optic cables are widely used for distributed temperature sensing applications in tunnels and petrochemical, steel, coal, and other large scale industrial enterprises. In addition, the temperature sensing cable can be used for health examinations in large construction projects such as bridges and warehouses.
