In the standard flame-resistant optical fiber cable for mine use, the fibers are positioned in a loose tube made of high modulus plastic. The tubes are filled with nonwoven fabrics of high density water-resistant filling compound .A steel wire, sometimes sheathed with polythene for cable with high fiber count, locates in the center of core as a metallic strengthening member. Tubes are stranded around the strengthening member into a compact and circular cable core. The PSP is longitudinally applied over the cable core which is filled with the filling compound to protect it from water ingress. Then a PE sheath is applied. At last, the cable is completed with a blue PVC sheath.
1.BT Loose tube, steel structure.
2.Selection of halogen-free flame retardant sheath, suitable of all kinds of coal mines.
3.Excellent mechanical and temperature performance guaranteed by the accurate excess fiber length.
4.Critical protection to fibers, based on the excellent hydrolysis resistance and strength performance of tube material and special filling compound filled in the tube.
