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 mating receptacle (transceiver or adapter) includes a receptacle hook and a housing with an opening that accommodates the receptacle hook in a flexed position as the optical connector makes connection with the mating receptacle by introducing the receptacle hook into an optical receptacle hook recess.

Abstract: Connector assemblies having an adjustable polarity are described. For example, at least two ferrules may be arranged in a housing of the connector assembly within independent frame plugs in a certain polarity. A top portion of the housing may be removed to allow access to the frame plugs. Accordingly, an installer may open the housing, switch the polarity of the ferrules, and then re-couple the top portion to the housing. In another example, the connector assembly may include a latch that may rotate about the connector assembly from a first polarity position to a second polarity position. The connector assembly may include a compression element that may facilitate the rotation of the latch when the compression element is compressed. In this manner, the latch may be rotated to a different polarity position to allow the connector assembly to be connected to an adapter using a different polarity.

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 MPO adapter.
