Abstract:
A ferrule for optical connector, comprising a fiber positioning hole, a pair of guide holes into which guide pins are inserted, and a connecting end face in which ends of said fiber positioning hole and said guide holes open, having a chamfer portion equivalent to a part of a surface of a body of revolution formed at each guide hole on the said connecting end face side, and said connecting end face is formed so as to have an angle relative to a plane normal to center axes of said pair of guide holes, and wherein a center axis of each chamfer portion is parallel to the center axis of each corresponding guide hole, and positioned in an area extending from the plane passing through both center axes of said pair of guide holes toward the side where the base end side of the connecting end face exists, andwherein when said connecting end face is formed so as to have an angle of 8Â° relative to the plane normal to the center axes of the two guide holes, said chamfer portions are formed so that an aperture size of each chamfer portion on said connecting end face is within a range of 1.05 to 2.0 times a diameter of said guide holes.
