GYFTY53 fiber optic cable structure is 250μm fiber into a high modulus material made of loose tube,
The loose tube is filled with water repellent. The center of the cable core is a non-metallic reinforced core (FRP)
For some core of the cable, the non-metallic reinforced core also need to squeeze a layer of polyethylene (PE).
Loose tube (and fill rope) around the center reinforcement core twisted into a compact and round cable core, cable core gap
Filled with water blocking filler. Outside the core of the cable wrapped in a layer of polyethylene inner jacket, double-sided coated steel (PSP) longitudinal package after the extrusion of polyethylene sheath into a cable

1. Has good mechanical properties and temperature characteristics
2. loose tube material itself has good water resistance 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. Single non-metallic center reinforced core
7. loose tube filled with special waterproof compounds
8. Complete core fill
9. Double-sided coated steel belt (PSP) to improve the anti-moisture permeability of the cable
10. Good water blocking material to prevent vertical penetration of cable
