Abstract: A multi-fiber, fiber optic connector may include a reversible keying arrangement for determining the orientation for plugging the connector into an adapter to thereby allow for a change in polarity of the connection to be made on site. The connector housing may be configured to engage with a removable key that may be engaged with the housing in at least two different locations to provide the plug-in orientation, or the housing may have slidably displaceable keys movable between multiple positions on the housing.

Abstract: A fiber optic connector having a ferrule that forms an optical connection with another fiber optic connector. An outer housing supports the ferrule and has a front end portion and a longitudinal centerline axis. The front end portion includes a front end face with a portion of the ferrule being forward of the front end face. The front end portion includes a protector that is shaped and arranged to protect the ferrule. The protector is arranged so that the fiber optic connector and another fiber optic connector of identical construction can, starting in the same orientation, be mated together by rotating said other fiber optic connector 180° about an axis perpendicular to the longitudinal centerline axis, aligning the longitudinal centerline axes and moving the fiber optic connectors along the longitudinal centerline axes until the fiber optic connectors are mated to form the optical connection.

Abstract: A fiber optic connector is spliced to an optical fiber provided by a sheathed optical fiber and an optical fiber pigtail. The connector houses a protective sleeve that secures the splice area from damage due to movement of optical fibers during connecter use. The protective sleeve retains the sheathed optical fiber at a first end and secures the protective sleeve to a distal end of a ferrule flange assembly at a second end.

Abstract: A reversible polarity fiber optic connector includes an outer housing including a polarity key for coupling the outer housing to a fiber optic receptacle in only one orientation. A ferrule assembly is received in 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 ferrule assembly forms an optical connection with the fiber optic receptacle. A boot assembly is releasably connected to the outer housing to enable the ferrule assembly to be inserted into and removed from the outer housing. The boot assembly includes a rotor rotatable between locked and release positions. The rotor includes a blocking portion to block disconnection of the boot assembly with the outer housing in the locked position and to permit disconnection of the boot assembly with the outer housing in the release position.

Abstract: Lockable connector and adapter assembly with a rear body having a shield to prevent unlocking of the connector from the adapter port unless the connector is unlocked with a key configured for the connector. The lockable connector is a MPO connector with a slidable outer housing configured to receive a key latch arm of specific configuration to unlock the MO connector from the adapter port. The key latch arms or separate keys form the combination unlocking the MPO connector from the adapter port.

Abstract: An in-line dust shutter formed as part an adapter. A hinged dust shutter assembly is secured to an adapter wall. A shutter plate covers an opening formed at either end of the adapter to prevent debris from entering the adapter and distorting the light signal between opposing fiber optic connectors. The shutter plate extends at angle alpha from a rotational axis. The shutter plate is biased closed by a bias spring place about a pin of the rotational axis.

Abstract: A multiple fiber push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and including a stepped portion extending from at least one pair of opposing exterior surfaces of the ferrule. A one-piece housing-backpost is provided having a distal end in a connection direction and a proximal end in a cable direction. The one-piece housing-backpost is configured to receive a ferrule spring and the ferrule from the distal end. The housing-backpost includes at least one resiliently-deformable ferrule-retaining protrusion extending from a sidewall to engage the corresponding stepped portion of the ferrule. The resiliently-deformable ferrule-retaining protrusion is configured to deform towards the housing-backpost interior sidewall as the ferrule is inserted from the distal end and to extend outward against the stepped portion of the ferrule when the ferrule is seated in the housing-backpost to maintain the ferrule in the housing-backpost.
