ALIGNMENT SYSTEM AND METHOD FOR CALIBRATING POSITION OF OPTICAL FIBER BORE FERRULE

摘要

The present invention discloses an alignment system for calibrating a position of an optical fiber (30) in a bore of a ferrule (20), comprising: an outer cylinder alignment element (100) for calibrating a center position of an outer cylinder of the ferrule (20), so that the center of the outer cylinder of the ferrule (20) is aligned with a center of the outer cylinder alignment element (100); a fiber core alignment element (300) comprising a fiber core (302) having a center aligned with the center of the outer cylinder alignment element (100); an optical vision system (411, 412, 421, 422) for identifying a center position of a fiber core (32) of the optical fiber (30) and the center position of the fiber core (302) of the fiber core alignment element (300); and a controlling and moving system for actively adjusting the position of the optical fiber (30) in the bore of the ferrule (20) under the guide of the optical vision system (411, 412, 421, 422), so that the center of the fiber core (32) of the optical fiber (30) is aligned with the center of the fiber core (302) of the fiber core alignment element (300), and so that the center of the fiber core (32) of the optical fiber (30) is aligned with the center of the outer cylinder of the ferrule (20), eliminating the insertion loss of the ferrule (20) due to a radial deviation between the center of the fiber core (32) of the optical fiber (30) and the center of the outer cylinder of the ferrule (20).
