1. A reversible polarity fiber optic connector comprising:
an outer housing having a front end and a rear end separated along a connection axis, the outer housing including a polarity key configured for engaging a fiber optic receptacle to permit coupling of the outer housing in only one orientation with respect to the fiber optic receptacle, the outer housing having an interior;
a ferrule assembly including a front body, a first ferrule and a second ferrule, the first and second ferrules being supported by the front body, the ferrule assembly being configured for mating reception in the interior of the outer housing in a first position corresponding to a first polarity of the fiber optic connector and in a second position corresponding to a second polarity of the fiber optic connector, the first and second ferrules projecting from the front end of the outer housing in both the first and second positions, the ferrule assembly being configured to form an optical connection with the fiber optic receptacle; and
a boot assembly releasably connected to the outer housing to enable the ferrule assembly to be inserted into the interior of the outer housing along the connection axis and to enable the ferrule assembly to be removed from the interior of the outer housing along the connection axis when the boot assembly is disconnected from the outer housing, the boot assembly configured to receive a cable, the boot assembly including a rotor operatively connected to the outer housing for rotation with respect to the outer housing about the connection axis between a locked positon and a release position, the rotor including a blocking portion, the blocking portion being configured to block disconnection of the boot assembly with the outer housing in the locked position, and configured to permit disconnection of the boot assembly with the outer housing in the release position.
