Butterfly drop cable (GJX(F)H) for access network
Product Description:
1. Outer sheath: black or white LSZH
2. Optical fiber
3. Reinforcement: FRP or KFRP or steel wire
The butterfly entry cable for access network (for indoor wiring) is made by placing the optical communication unit (optical fiber) in the center, placing two parallel non-metallic reinforcements (FRP or KFRP) or metal reinforcements on both sides, and finally, extruding black or colored polyvinyl chloride (PVC) or low-smoke halogen-free materials (low-smoke, halogen-free, flame retardant) sheath.
Features and applications
● Simple structure, light weight and strong practicability;
● Unique groove design, easy to peel off, easy to connect, simplify installation and maintenance;
● Indoor wiring.
