The fibres,250μm,are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water-resistant filling compound.A steel wire,sometimes sheathed with polyethylene(PE) for cable with high fiber count,locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core,which is filled with the filling compound to protect it from water ingress,then,the cable is completed with a PE sheath
Selected high quality optical fiber ensure the optical fiber cable have good transmission properties
The unique fiber excess length control method provides the cable with excellent mechanical and environmental properties
Very strict material and manufacturing control guarantees stable product quality.
Total cross-section water-resistant structure make cable has an excellent properties of moisture resistance
Special jelly filled in the loose tube provides the fibers with critical protection
