GJFZY53-FR refractory fiber optic cable is 250μm optical fiber into a high modulus material made of loose tube,
The loose tube is filled with water repellent. The center of the core is a non-metallic reinforced core, for some
Core number of fiber optic cable, non-metallic reinforcement core also need to squeeze a layer of polyethylene. Loose tube (and filled rope)
Around the center to strengthen the core twisted into a compact and round cable core, longitudinal package after squeezing a layer of flame retardant inner jacket, double
Coated steel belt longitudinal package after the extruded flame retardant jacket into a cable

1. Has good mechanical properties, temperature characteristics and fire resistance
2. The loose tube material itself has good resistance to hydrolysis and high strength
3. The tube is filled with special ointment to protect the fiber
4. Good resistance to stress and softness
5. Use the following measures to ensure the waterproof performance of the cable:
6. Rigorous processing technology, scientific and rational design
