Abstract:
A fiber bulge (“bulge”) formed in an end of an optical fiber for positioning the optical fiber in a ferrule bore is disclosed. An energy source is controlled to direct focused energy to the end of the optical fiber extended from the front end face of the ferrule to expose and melt the end of the optical fiber into a bulge of desired geometry and size. The bulge comprises a cross-sectional region having an outer surface having a minimum outer diameter larger than the inner diameter of the ferrule bore. Thus, the optical fiber may be pulled back in the ferrule bore such that at least a portion of the outer surface of the interface region of the bulge interferes with and engages the front opening of the ferrule bore to position the fiber core within the ferrule bore.
