optical cables that resistant to biological hazards caused by rodents,termites and birds,etc. after installation.Optical cables are often damaged by rodents.Termites not only bite,but also release formic acid to the cables.We design methods include physical(include metallic and glass fiber armor and nylon sheath) and chemical methods(Spicy additives ) agsinst biological hazards
Accurate process control ensuring good mechanical and temperature performances
The material of loose tubes with good hydrolysis resistance and high strength
Tube filling compound providing the key protection for fibres
Excellent crush resistance and flexibility
Non-Metallic FRP wires armors providing excellent anti-rodent performance
