Abstract
A fiber optic connector has at least two optical fibers therein have end faces that are positioned such that they are directed in different directions. The end faces can be oriented relative to a key that is provided on a fiber optic connector housing that has a central opening in the main body of the fiber optic connector.

A duplex fiber optic connector comprising:
- a housing having a length along a longitudinal axis, a width along a lateral axis and a height along a transverse axis, the height being larger than the width,
- wherein the housing has a top side, a bottom side, and a pair of opposing sides joining the top side to the bottom side, the housing further defining a central opening at a terminal one of the opposing sides, the terminal one of the opposing sides defining an end face of the housing that extends around a continuous circumference thereof;
- a first ferrule supporting a first optical fiber, the first ferrule having an end face at an angle relative to the longitudinal axis;
- a second ferrule supporting a second optical fiber, the second ferrule also having an end face at another angle relative to the longitudinal axis, wherein, at least one of the ferrules is in a first polishing position for polishing the end face and a second mating position for mating the duplex fiber optic connector with another duplex fiber optic connector, and wherein when the first and the second ferrules are in the second mating position, the angle of the first ferrule is 180 degrees offset from the angle of the first second ferrule in the second mating position, the first ferrule and the second ferrule being at least partially surrounded by the housing;
- and
- a key located on the top side of the housing,
- wherein the key protrudes outwardly of the housing,
- wherein the first ferrule and the second ferrule each begin at a position within the housing and rearwardly of the central opening of the housing,
- wherein the respective end faces of the first ferrule and the second ferrule are exposed at a front end of the housing by protruding beyond the front end of the housing,
- wherein the duplex fiber optic connector has a first polarity in which the angle of the end face of the first ferrule and the angle of the end face of the second ferrule are positioned relative to the key, and a second polarity in which the angle of the end face of the first ferrule and the angle of the end face of the second ferrule are positioned relative to the key the same as in the first polarity,
- wherein the first ferrule and the second ferrule are at a same fixed orientation relative to the housing in both the first polarity and the second polarity of the duplex fiber optic connector.
