ABSTRACT:
A reinforced optical fiber including a single optically guiding fiber, a nonmetallic intermediate layer of flexible strength members conforming to the fiber and tapering at a pre-determined rate to expose the fiber, and a metal sheath around the fiber and intermediate layer conforming to the intermediate layer and terminating prior to the taper of the intermediatae layer. A method of manufacturing the fiber sheathed in a metal casing including the steps of separately feeding the optical fiber surrounded by the intermediate layer and the casing material into a die, and drawing the encased fiber from the die. The method also includes measuring and adjusting the tensions of the fiber, casing material, and encased fiber. A die for sheathing the optical fiber includes a die block, an entrance for the fiber and casing material, a continuous and smooth shaping chamber, and an exit for the encased fiber.
