Claims

[Claims for Utility Model Registration] (1) An optical connector plug consisting of a ferrule containing an optical fiber, a housing surrounding the outer periphery of the ferrule, and a nut screwed onto one end of the housing; The end face of the ferrule at the end is polished into a spherical shape, and when the numerical aperture of the optical fiber is NA and the maximum refractive index of the core of the optical fiber is n, the end face of the open end of the ferrule is s for the plane perpendicular to the axis
An optical non-reflection terminator, characterized in that the ferrule has an inclined end surface inclined at an angle of in ^-1 NA/n or more, and a terminal end of the ferrule is located within the housing. (2) The optical non-reflection terminator according to claim 1, wherein a part of the end face of the open end of the ferrule, including the core, forms the inclined end face.
