<p>A hybrid cable (16) includes an optical fiber (12) and a multifilament (14) twisted and drawn or swaged electrical conductor. According to one embodiment, the filaments of the multifilament (14) twisted and drawn or swaged electrical conductor are twisted about the optical fiber (12) and then drawn through one or more dies or swaged. In a second embodiment, a metal tube (120) is drawn through one or more dies, an optical fiber (112) is provided in the tube, and then the tube is drawn again with the optical fiber (112) contained therein to result in a drawn filled tube having a central optical fiber. The drawn filled tube (120) is then used a central filament and a plurality of conductive filament (114) are twisted and about the central filament and the twisted assembly is then drawn or swaged to result in a hybrid cable. In a third embodiment, a multifilament twisted and drawn or swaged cable is formed with a central filament harder than the surrounding filaments.</p> |
