Fiber-optic cable OKM-A(S) for suspension on overhead power lines.
Fiber-optic cable OKM-A(S) is designed for suspension on overhead power lines, urban lighting pillars, between buildings in case of high requirements of crush strength.
Cable contains polymer tubes with optical fibers. Polymer tubes are SZ-stranded around FRP central strength member in PE-jacket. Interstice inside and between tubes is filled with hydrophobic filler. Cable core is wrapped by yarns. High modulus aramid yarn layer covers cable core. Outer jacket of high density polyethylene is imposed on the cable core.
