Abstract
A rotation and alignment device for assembling of an optical fiber connector with a lower connection loss. This device image-processes the distribution of optical intensity of light emitted from an end surface of an optical fiber of a ferrule and derives an optical peak intensity point of the end surface of the optical fiber such that the point is placed in a predetermined region of a rectangular coordinate system. This device comprises a rotation and marking part for controlling a rotational position of a marker with respect to the ferrule and marking the optical peak intensity point on an outer surface of the ferrule. A ferrule fixture part is coupled to the rotation and marking part and fixes the ferrule such that the outer surface of the ferrule is marked with the optical peak intensity point by the marker. A vertical supporting part supports the rotation and marking part and the ferrule fixture pat. An optical system and fiber alignment part is mounted on the support rail part and magnifies and aligns the end surface of the optical fiber of the ferrule. The support rail part assures the rotation and marking part and the optical system and alignment part of a desired horizontal location.
