<P>PROBLEM TO BE SOLVED: To allow smooth removal of a coating of a coated optical fiber. <P>SOLUTION: A mechanical splicing part for butt joint between a built-in optical fiber and an inserted optical fiber is provided with a coating removal part for removing a coating of a coated optical fiber, and a coating removing member constituting the coating removal part includes a coated optical fiber insertion-side portion having a coated optical fiber insertion hole, and a coating removal-side portion having a bare fiber insertion hole and a coating removing action portion for removing the coating of the coated optical fiber. An inner diameter of the coated optical fiber insertion hole is approximately equal to an outer diameter of the coating of the coated optical fiber, and the bare fiber insertion hole has an intermediate part having an inner diameter approximately equal to an outer diameter of a bare fiber and has, on the entrance side, a taper hole expanded toward the entrance and has, on the exit side, a diameter larger than the outer diameter of the bare fiber. Collisions with an inner wall of the bare fiber insertion hole, of a front end edge of the bare fiber which has had the coating removed therefrom are reduced, and disconnection of the bare fiber due to axial misalignment from a centering groove for butt joint can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
