Abstract
A method for assembling a fiber optic connector utilizes a manufacturing fixture with multiple fingers that are removably affixed to an outer surface of a ferrule holder having at least one keying feature. A core position of an optical fiber relative to a ferrule retained by the ferrule holder is determined, followed by relative rotation between the ferrule holder and the manufacturing fixture to place the core position in a preferred angular orientation, and a housing is affixed over the ferrule holder the maintain the angular orientation of the core position, followed by removal of the manufacturing fixture. A ferrule holder includes at least one keying feature and at least one channel extending in a circumferential direction along an outer surface of a body structure, with a plurality of recesses extending in an axial direction along the outer surface.
