Seamless Tube Armored Fiber Optic Cable

The seamless tube armored fiber optic cable that we manufacture is an excellent sensor cable mainly used for temperature and pressure sensing in various industries such as oil tanks, mining and chemical plants. With this temperature and pressure sensor cable, accidents that frequently occur in these industries can be prevented.

This armored fiber optic cable is composed of a bare fiber, oil, a seamless stainless steel tube and a PVC/LSZH jacket. This structure brings a high tensile strength, crush resistance, a compact size, and an unmatched steel performance to this fiber cable.

Product Features
1. This armored fiber optic cable features a simple structure and small size as well as prominent mechanical properties and transmission performances.
2. Due to its seal design, electrochemical corrosion resistance, oil and water blocking performances, this fiber optic sensor cable is suitable for all kinds of harsh environments.
3. This fiber optic cable also has an excellent resistance to high temperatures and EMI.
