  • Publication number: 20200081198
    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.

  • Patent number: 10578813
    Abstract: An optical fiber connector assembly comprising an MPO connector and a push-pull tab. The connector may have an outer housing and an inner housing extending beyond a rear end of the outer housing, the outer housing having a first protrusion and the inner housing having a second protrusion positioned at a distance from the first protrusion. The push-pull tab may comprise a main body and an extender coupled to the main body, the main body having a plurality of walls forming a passageway configured to receive the connector, the plurality of walls including a first wall having a window sized according to the distance between the first and second protrusions and configured to receive the first and second protrusions. In another embodiment, the push-pull tab may comprise a first piece and a second piece configured to couple to each other to form a passageway for receiving the connector.

  • Publication number: 20200064564
    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.

  • Publication number: 20200003963
    Abstract: A fiber optic connector with a rotatable housing integrated with a connection member for converting the connector from a first polarity to a second polarity, and a manipulator assembly comprising the rotatable housing and a locking member movable between a locked position and an unlocked position, the manipulator assembly being coupled to the connection member such that the manipulator assembly and the connection member rotate conjointly about the axis of rotation, and when in locked position connector polarity cannot be changed.

  • Patent number: 10520686
    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 a 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.

  • Patent number: 10295759
    Abstract: An optical connector is provided having a ferrule configured to house one or more optical fibers. An inner housing is provided to hold the ferrule and has a distal end in a connection direction and a proximal end in a cable direction. An outer housing at least partially surrounds the inner housing. One or more resilient forward biasing projections extend from one or more of the outer housing or the inner housing for biasing the outer housing towards the distal end of the inner housing. The resilient forward biasing projection may be integrally formed with either the inner housing or with the outer housing.
