FEEDER LINE COMPOSITE OPTICAL FIBER CABLE

摘要

PROBLEM TO BE SOLVED: To provide a composite optical fiber cable with a feeder line requiring no securing of electric power when an ONU(optical network unit) is disposed, and capable of setting the ONU in an optional site. SOLUTION: This fiber cable is constituted by assembling collectively feeder lines 26 each of which is provided with a coating layer on conductor lines 23, 23, and optical units 30, on an outer circumference of a tension member 22, 0.2% proof-stress of the conductor line 23 is 7-50 kg/mm2 and its outside diameter is 0.8-3 mm.
