Uni-Tube Single Mode Fiber Optic Cable is a compact outdoor optical cable designed for telecom, data communication, and network infrastructure applications. Featuring a PBT loose tube construction, galvanized steel strength members, and robust environmental protection, it delivers reliable long-distance optical transmission and mechanical durability. Suitable for aerial and duct installations, the cable is designed to perform in demanding outdoor environments while maintaining stable signal quality.
Note 1: Tensile strength and crush resistance shall vary as per the cable diameters, steel rod diameter and thickness of sheath.
