Abstract: A fiber optic connector assembly includes an outer connector housing defining an optic axis in a through passage. A first key is disposed in the passage at a given position angularly about the axis. An inner optical fiber plug terminates an optical fiber and is disposed in the passage and includes a second key movably positionable about the periphery of the plug to different selected positions of rotational adjustment for the plug. The second key is fixable at any selected position on the plug and is lockable with the first key on the housing to fix the angular position of the plug relative to the housing and, thereby, fix the rotational position of the optical fiber angularly of the optic axis.

Abstract: A cleaner is provided for cleaning the end surface area of a ferrule of a fiber optic connector. The cleaner includes a housing having a mating portion for mating the cleaner with the connector. A cleaning head is movably mounted on the housing for movement across the end surface area. A motor is mounted on the housing and is coupled to the cleaning head for moving the cleaning head in response to operation of the motor. An air jet is mounted on the housing for directing a stream of a cleaning medium toward the cleaning head to remove residue from the end surface area. An exhaust is provided on the housing for removing and evacuating residue from the end surface area. A plurality of the cleaners are mounted on a dummy circuit board for cleaning the end surface areas of the ferrules of a plurality of fiber optic connectors mounted in a given pattern on a backplane of a chassis.
