A method for manufacturing a fiber optic connector assembly, comprising: providing a ferrule having a first fiber and a cable having a second fiber; adjusting the ferrule to locate the first fiber at a first predetermined orientation, and adjusting the cable to locate the second fiber at a second predetermined orientation; and inserting the first fiber located at the first predetermined orientation and the second fiber located at the second predetermined orientation into a alignment tool received in a housing of a fiber optic connector. Wherein the first and second predetermined orientations are set so that a distance between a center of a fiber core of the first fiber and a center of a fiber core of the second fiber is equal to an absolute value of a difference between a distance from a center of a coat layer to the center of the fiber core of the first fiber and a distance from a center of a coat layer to the center of the fiber core of the second fiber when the first fiber located at the first predetermined orientation and the second fiber located at the second predetermined orientation are inserted into the alignment tool.
