  • Underwater optical fiber cable having optical fiber coupled to grooved metallic core member
    Patent number: 5224190
    Abstract: An optical fiber cable (20) includes a longitudinally extending copper core member (34). The core member is formed with at least one groove (36) in which is disposed at least one optical fiber. The optical fiber is coupled sufficiently to the core member preferably by an ultraviolet light energy cured material to substantially inhibit relative movement between the optical fiber and the core member when forces are applied to the cable. A sheath system which includes a plastic jacket (112) is disposed about the core member. The sheath system includes a strength member system which includes longitudinally extending copper wires (105, 105) and steel wires (101, 107). Disposed about the steel and copper wires is a steel shield (110) which provides hermetic protection for the optical fibers.
