1. A fiber optic connector, comprising:
a housing comprising a rear portion defining a rear end, a front portion defining a front end, and a longitudinal passageway extending from the rear end to the front end and a locking feature for securing the optical mating of the fiber optic connector, wherein a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion, wherein the transition region comprises a threaded portion and the locking feature is a subtractive portion from the primitive geometry of the rear portion for securing the optical mating of the fiber optic connector configured as a ramp with a ledge; and
a ferrule comprising a fiber bore extending from a rear end to a front end.
