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.

Abstract: An integral fan-out connector assembly for fiber optic cables includes a connector housing that provides an integrated fan-out housing and connection adapter. The fan-out connector housing may be configured with a variety of cable adapters, and may be installed as a ‘plug and play’ type solution where it will be ready to accept a feed cable for use when needed. A bracket may support the fan-out system on a support structure as a pole. The bracket can facilitate plug-and-play use of the fan-out system.

Abstract: A fiber optic ferrule adapter for mating a multi-fiber optic ferrule and a multi-fiber optic connector includes a holder having a cavity where a multi-fiber optic ferrule is held therein, and a receptacle housing with an opening that allows the insertion of a fiber optic connector. The holder has a top opening for receiving the ferrule into its cavity; and two protrusions, which are respectively protruded from each interior side walls of the holder, for latching the ferrule in place inside the cavity. The holder includes a groove recessed on the interior walls of the cavity for catching a ridge on the ferrule so as to prevent any longitudinal movement of the ferrule inside the cavity. The cavity may include a slope next to an interface between the cavity and receptacle housing for allowing the sliding in-and-out of the ferrule at an angle to the top of the holder opening.

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 latch component that is removably connected to the housing. The connector may furthermore include a push-pull tab removably connected to the housing and configured to move horizontally along the outer surface of housing when a biasing force is applied in at least one of a forward direction and a rearward direction. Accordingly, the push-pull tab can compress the latch component when moving horizontally along the housing, and an inverted ramp at a proximal end of the push/pull, the ramp aides in depressing the latch downward to release the connector from a receptacle.

Abstract: An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A connector is released by pulling distally on boot assembly until receptacle hook is displaced from receptacle hook recess at a proximal end of connector.

Abstract: An optical connector holding one or more LC-type optical ferrules is provided. The optical connector includes an outer housing, pin keep, and two pins. One pin acts as a push/pull mechanism to release the connector from the adapter. The pin keep has two side clips with one of two side clips having an alignment key on a top surface. The alignment key engages a corresponding surface in the adapter housing to aid in polarity setting of the connector with the adapter. The adapter has a panel mounting clip that contains one or more latches that engage and retain the connector in the adapter housing. The panel clips and surfaces of the connector are constructed to reduce the overall size of the connector and adapter. The adapter has a plural of internal ribs forming one or more channels.

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 latch component that is removably connected to the housing, wherein the latch component is configured to rotate around the housing. The latch component may have a first locking element configured to engage a second locking element to prevent rotation of the latch component in at least one of a first polarity position to a second polarity position. The connector may further more include a push-pull tab removably connected to the housing and configured to move vertically along the housing when a biasing force is applied in at least one of a forward direction and a rearward direction. Accordingly, the push-pull tab can compress the latch component when moving vertically along the housing.
