Abstract: Reduced-profile connection components are described. The reduced-profile connection components are configured to connect various data transmission elements, including cables, network devices, and computing devices. A non-limiting example of a connection component includes a fiber optic connection component, including connectors, adapters, and assemblies formed therefrom. In some embodiments, the connection components may include mechanical transfer (MT) and multi-fiber push-on/pull-off (MPO) connection components, such as MT ferrules and MPO adapters. The reduced-profile connection components configured according to some embodiments have a smaller profile and/or require less parts to achieve a connection compared to conventional connection components. In some embodiments, the reduced-profile connection components may be used with conventional connection components. For example a reduced-profile connector may use a conventional MT ferrule to establish a connection within a conventional MPG adapter.

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: A micro connector kit includes first and second ferrules and first and second micro connector ferrule housings. Each first and second micro connector ferrule housing defines a cavity sized and shaped to receive a respective one of the first and second ferrules with the first and second ferrules being disposed in closely spaced relation with the respective first or second micro connector ferrule housing when in each cavity. The first and second micro connector ferrule housings can be releasably coupled together such that the first and second ferrules form an optical connection when the first and second micro connector ferrule housings are coupled together. The first and second micro connector ferrule housings have first and second connection structure for releasably coupling the first and second micro connector housings together.

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.
