  • Patent number: 5234198
    Abstract: Optical fiber (20) which may be disposed in the form of a ribbon (28,30), for example, is caused to become disposed in a conduit (42) such as a duct which may exist in the field by introducing the optical fiber and a pressurized liquid transporting medium (37) into the conduit. The liquid transporting medium is effective to cause the optical fiber to be moved along in the conduit to cause a leading end of the fiber to emerge from a far end of the conduit and be accessible for connective arrangements, for example.
