Abstract: A multi-polarity fiber optic connector is configured to provide a plurality of connector polarity options. Two LC connectors are grouped together using a duplex cable boot assembly which is secured over a backpost extending from a plug frame of each LC connector. Each LC connector has a release latch attached to the outer surface of the plug frame. A dual release latch has a hook that secures the dual release latch to the duplex cable boot. The dual latch release is configured to depress each LC connector latch release together. To change the duplex LC connector from a first polarity to a second polarity, a user pulls on one of the two cable boots that makes up the duplex cable boot assembly and then rotates each LC connector housing, or the user pulls on the dual latch release and then rotates each LC connector housing. User rotates each LC connector housing 180 degrees about a longitudinal axis of the LC connector to change the connector polarity from a first polarity to a second polarity where the first polarity is opposite the second polarity.

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: A LC type connector assembly with a clip on, clip off push/pull boot is described herein. A cable boot is recessed to accommodate one or more tabs of the clip-on push/pull boot, while the cable boot has one or more protrusions for securing the cable boot to a back body of the connector. Thus, the push/pull clip is integrated with a cable boot assembly that allows a user to apply a distal force to remove or insert the connector assembly into the adapter housing. The push/pull clip is configured for use to release a LC connector type from a receptacle port with or without an anchor device within the port.

Abstract: Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a push/pull clip that is configure to depress a protrusion that rotates down a connector device to remove the connector assembly from an adapter. The push/pull clip is integrated with a cable boot assembly that allows a user to apply a distal force to remove or insert the connector assembly into the adapter housing. The push/pull clip is configured for use to release a MPO and LC connector type from an adapter.

Abstract: A multiple push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and a housing having a distal end in a connection direction configured to hold the ferrule. The housing further includes a pair of proximal apertures and at least one proximal groove. A backpost has a distal end that urges the ferrule toward the distal end of the housing and a proximal end configured to receive a crimp ring. The backpost includes a pair of proximally extending latch arms that reverse latch in the proximal apertures of the housing. To strengthen the connector in side-loading environments, the backpost further includes a reinforcing rib that is received in the housing proximal groove. In a further aspect, the proximal end of the backpost may include a neck with an approximately curved side profile that, following crimping with a stepped crimp ring, results in an angled crimp.
