Abstract
A ferrule terminated optical fiber in which the fiber is held only approximately on the axis of the ferrule on the sides of which flat reference surfaces are subsequently machined. Machining is performed to a predetermined distance from the center of a fiber core, the position of which is revealed by launching light into the fiber from the other end. Providing the reference surfaces as a last manufacturing step avoids the problems of cumulative errors which arise from assembling parts having dimensional tolerances, together with the error resulting from distortion liable to occur during the setting of the adhesive holding a fiber in a ferrule.
