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 connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

Abstract: Connector assemblies having an adjustable polarity are described. A connector assembly having an adjustable polarity comprises a housing and a locking component configured to couple to the housing, the locking component including a compression element. The connector assembly further comprises a latch component configured to rotate around the locking component when the compression element is compressed to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position.

Abstract: A behind-the-wall optical connector an outer housing configured to be inserted into an adapter with a corresponding inner surface, a ferrule included in an annular collar to mate with a corresponding projection at an adapter opening, and a latch attached to one side of housing configured to lock the connecter into an adapter opening. The latch is further configured with a locking channel and guide to accept a pull tab with a catch at one end, the pull tab releases the connector from the adapter opening when the tab is pulled rearward or away from the adapter.

Abstract: A behind-the-wall optical connector includes a ferrule having an annular collar projecting outwardly from a section of the ferrule and a plug frame receiving the ferrule in a central bore thereof, the plug frame including one or more resiliently-biased latches for gripping the ferrule annular collar to retain the ferrule within the plug frame. The optical connector may be fabricated inexpensively due to the low number of components. An optional boot may be provided. An insertion tool for assembling the optical connector is also described.

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.

Abstract: An optical connector has a connector housing assembly for holding one or more ferrules, the connector housing assembly having a height align a vertical alignment axis and a width perpendicular to the height. The connector housing assembly includes an inner front body and an outer release component, the outer release component being movable in relation to the inner front body between a front position and a back position. The optical fiber connector is configured to mate with a receptacle having an upper receptacle hook such that the upper receptacle hook is received in the upper receptacle hook recess and latches with the upper hook retainer surface when the outer release component is in the front position and such that the upper ramp lifts the upper receptacle hook out of the upper receptacle hook recess when the outer release component moves to the back position.

Abstract: An optical fiber connector with a housing configured to hold a plurality of optical fiber ferrules is selectively reconfigurable between a first configuration and a second configuration different from the first configuration. The housing can have different widths in the first and second configurations. The ferrules can have different ferrule arrangements in the first and second configurations. The optical fiber connector can be mateable with different types of receptacles in the first and second configurations. Reconfiguration can be achieved by disconnecting a rear housing from a plurality of front housings at first set of attachment points, rotating the rear housing 180° in relation to the front housings, and attaching the rear housing to the front housings at the second set of attachment points.

Abstract: A multifiber ferrule has a generally forward-facing angled ferrule contact surface that is skewed with respect to the widthwise axis of the ferrule such that the angled ferrule contact surface defines a widthwise skew angle with respect to the widthwise axis. A multifiber optical connector has a connector housing assembly that holds at least one of this type of ferrule. The connector housing assembly can hold two such ferrules so that the ferrule contact surfaces are angled in opposite widthwise directions and so that a broad side of the first ferrule opposes a broad side of the second ferrule in parallel, spaced apart relationship therewith. A polarity-changeable multifiber optical connector is also provided that includes a multifiber ferrule with a generally forward-facing ferrule contact surface at an oblique angle to the longitudinal axis.

Abstract: A field installable fiber optic connector for use with polymer optical fibers includes a housing that releasably connects to another optical device. A mechanical termination assembly is located in the housing to mechanically terminate a plurality of individual fibers of the polymer optical fibers. Ferrules are supported by the housing. Each ferrule is positioned to receive one of the individual fibers from the mechanical termination assembly.

Abstract: An optical connector assembly a first structure and a second structure, the two structures secured together using a retention structure to form a hybrid assembly. The retention structure uses a slot apex located in a slot channel for securing at least one latch pin of a coupling nut to an adapter housing forming the ingress protected connector without the use of a bias spring. The hybrid assembly is designed to resist water or debris ingress, and may eliminate the use of a bias force to further resist separating the hybrid assembly.
