OPTICAL FIBER CABLE DRAW ANCHORING JIG

摘要

PROBLEM TO BE SOLVED: To solve the problem that an optical fiber cable becomes small in radius of curvature at the exit and entrance of a draw anchoring jig to increase in light loss and the problem that a slip stopping projection intrudes into the optical fiber cable too much and a coated optical fiber of the optical fiber cable curves to increase in light loss.

SOLUTION: An optical fiber cable draw anchoring jig equipped with a sheath member through which the optical fiber cable is run and a wedge member which is inserted into the sheath member to clamp and fix the optical fiber cable and sheath member together is characterized in that an arcuate support part which can support the optical fiber cable in a curved state is formed at an entrance bottom part and an exit bottom part of the sheath member, the radius of the curvature at the support part is≥2 mm. The slide stopping projection is formed on the internal surface of the sheath member and 0.01 mm≤a and a/b≤0.28 hold for the height (a) of the slide stopping projection and the thickness (b) of the optical fiber cable.
