Leather wire optical cable is commonly known as indoor suspended wiring optical cable. With the good development momentum of the domestic fiber optic access market, fiber optic access has become a hot topic in the field of optical communication. In fiber optic access engineering, indoor cabling close to users is the most complex aspect, and the bending and tensile properties of conventional indoor optical cables can no longer meet the requirements of FTTH (Fiber to Home) indoor cabling.

The disc-shaped fiber optic cable for access network (for indoor wiring) is made by placing the optical communication unit (fiber optic) in the center and placing two parallel non-metallic reinforcement pieces (FRP) or metal reinforcement components on both sides. Finally, black or colored polyvinyl chloride (PVC) or low smoke halogen-free material (LSZH, low smoke, halogen-free, flame retardant) sheaths are extruded.
