Description：Optical fibers are housed in loose tubes that are made of high-modulus plastic and filled with tube-filling compounds. Loose tubes are stranded around the non-metallic central strength member (FRP). Polyethylene (PE) is extruded as the inner sheath, and then aramid yarns or glass yarns are applied over the inner sheath to enhance tensile strength for special applications. The cable is completed with PE outer sheath.

Description：The ASU optical cable is a type of optical fiber cable designed for outdoor aerial installations. It is a non-metallic cable and does not require additional support elements like steel messenger wires for aerial installations. The fiber optic cable structure puts the colored fiber in the PBT loose tube, and two FRP as strength members, The Cable surface is extruded with a PE outer sheath. It also belongs to overhead fiber optical cable.

Description：Optical fibers are housed in loose tubes made of high-modulus plastic and filled with tube-filling compounds. Loose tubes are stranded around the central strength member. The cable core is wrapped with corrugated steel tape. This part integrated with a steel wire messenger is sheathed with polyethylene (PE) in a Figure-8 shape.

Description：Optical fibers are housed in a loose tube made of a high-modulus plastic. The tubes are filled with a water-blocking compound. The cable accompanied by the stranded steel wires as the supporting part is completed with a polyethylene (PE) sheath to be Figure-8 structure.
