ABSTRACT:
A steam resistant optical fiber cable for use adjacent underground steam ducts in metropolitan locations. The optical fiber cable comprises polyethersulfone loose tubes for enhanced hydrolytic stability and a welded aluminum tube swaged over the fiber core to provide moisture imperviousness. The welded aluminum tube is bonded to the fiber core with an intermediate resin barrier layer to provide resistance to repeated cyclic flexing of the cable.
