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: 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.

Abstract: An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.

Abstract: An adapter for mating optical fiber connectors may include an internal configuration that essentially holds the ferrules of the connectors in alignment when a force is applied to the connector in a sideways direction. An internal plate may be provided to essentially prevent displacement of the mating ends of the ferrules with respect to the adapter housing and one another.
