<p><P>PROBLEM TO BE SOLVED: To solve a problem that an optical fiber is damaged because a large force is locally imparted to the optical fiber. <P>SOLUTION: The holder is equipped with two cylindrical drums 6a, 6b which are arranged with a fixed space apart and in which each groove 3 is spirally formed. One end and the other end of an optical fiber 1 are each wound along the groove 3 of the two cylindrical drums 6a, 6b, transferring the two drums 6a, 6b in the direction opposite to each other until a desired tension is applied to the optical fiber 1. <P>COPYRIGHT: (C)2003,JPO</p> |
