A method of terminating an optical fiber having an inner core with a fiber optic connector including a ferrule having a micro-bore and an end face with a mating location is disclosed. The method includes determining a bore bearing angle of a bore offset of the micro-bore in the ferrule; determining a core bearing angle of a core offset of the inner core in the optical fiber; orienting the ferrule and the optical fiber relative to each other to minimize the distance between the inner core and the mating location; heating the ferrule to an processing temperature above room temperature; and coupling the optical fiber to the micro-bore of the ferrule. The size of the micro-bores and optical fibers may be selected to maximize the number of interference fits in a population of ferrules and optical fibers while minimizing failed fittings between the ferrules and optical fibers in the populations.

Method for making a low-loss fiber optic connector

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.

A non-cylindrical hypotube is disclosed, such as for use in OCT and endoscopy. The hypotube is defined by a non-cylindrical, rotationally symmetric tube and has an interior, a proximal-end section with an outer diameter Da distal-end section with an outer diameter Dand a middle section between the proximal-end and distal-end sections and having an outer diameter Dwherein D&#x3c;Dand D&#x3c;DThe distal-end section is sized to accommodate the optical probe and includes an outer surface with an aperture that allows for optical communication therethrough.
