Stripper for removing coating from optical fibers

An optical fiber stripper is formed with an interior cylindrical elongate passage for housing a fiber length and for containing stripper fluid. To assure ample room for expansion of the fiber coating during stripping, the passage has a greater volume than that of the coated fiber after the coating expands from contact with the fluid. The passage has a fluid inlet at its interior end for introducing stripping fluid. A relatively sharp shoulder disposed at the interior end of the passage and formed by a short cylindrical neck section coaxial with the passage has a diameter only marginally greater than the diameter of the coated fiber. Once the coating in the passage is softened by the stripper fluid, the fiber is withdrawn allowing the shoulder to cleanly strip away the coating. Advantageously, the stripper is made from graphite, so that any incidental contact with the fiber during the draw-stripping operation has no deleterious effect on the fiber surface.
