ASU central loose tube type all-dielectric optical cable
ASU all-dielectric optical cable adopts central loose tube structure, and the optical fiber is sheathed in a loose tube made of high-modulus polyester material, and the tube is filled with waterproof compound. The loose tube and two high-strength nonmetallic central reinforcing cores (FRP) are twisted into a compact cable core, and a tear rope convenient for cable stripping and some filling yarns are added into the cable core. Finally, the polyethylene (PE) outer sheath is extruded to form a cable.
