PBT tube optic fiber cable is used for temperature and pressure inspection,structure of which is bare fiber+oil+PBT tube+aramid yarn+jacket.This structure performs high tensile strength,light weight and waterproof.
1、Non-metallic structure,good mchanical ,transmission and environmental property;
2、PBT tube protects fibers inside,small diameter and high strength mechanical property
