A ferrule that is connected to the end of an optical fiber has a cylindrical portion at its outer end that has a short length and a conventionally small diameter. At its other end, the ferrule has a larger diameter cylindrical portion, and it has a conventional cone shaped portion connecting the two cylindrical portions. A tunnel has an opening with a corresponding shape for receiving the ferrule. The smaller diameter cylindrical portion at the outer end of the ferrule accurately positions the end of the optical fiber on the axis of the tunnel. The larger diameter cylindrical portion prevents the end of the fiber from being tipped with respect to the axis of another fiber or component connected to the other side of the tunnel.
