求項１記載の光フアイバ終端器。[Scope of Claim for Utility Model Registration] 1. An optical system consisting of a ferrule in which a short optical fiber is fixed on its central axis, a spring that presses the ferrule toward its tip, and a fastening structure that fastens it to an optical connector. In the fiber terminator, the end face of the tip of the ferrule connected to the optical connector is optically polished with the core of the optical fiber as the apex, and the end face of the rear end of the ferrule is perpendicular to the optical axis. 1. An optical fiber terminator characterized in that optical polishing is performed at a slight angle with respect to the direction, and a light diffusing plate is disposed near the obliquely polished surface. 2. The optical fiber terminator according to claim 1, wherein a space between the rear end of the ferrule and the light diffusing plate is filled with a matching agent having substantially the same refractive index as the optical fiber core.
