METHOD FOR ALIGNING MULTIPLE OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To facilitate the setting of the accuracy of the pitches of optical fibers and the lengths of the optical fibers. SOLUTION: A second ferrule 18 is coupled by means of guide pins 20 to a first ferrule 16 inserted with the plural optical fibers in its fiber holes. The optical fibers are passed into the fiber holes of the ferrule as well. The first ferrule 16 and the optical fibers are fixed by adhesives and the second ferrule 18 and the optical fibers are fixed by wax. The end faces of the second ferrule 18 are polished and are then heated, by which the second ferrule 18 is removed from the optical fibers. As a result, the alignment of the optical fiber front ends in 7μm order is possible The length (g) of the optical fibers may be changed by inserting a spacer 22 between both ferrules 16 and 18.
