Abstract: An optical fiber connector assembly comprises at least one connector having a latching arm for coupling to an adapter, and a remote release tab having a protrusion configured to cooperate with the adapter to depress said latching arm when the remote release tab is pulled relative to the adapter. The optical fiber connector assembly may further be configured to allow reversing its polarity.

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 internal alignment slots configured to accept a corresponding alignment key on connector outer housing to ensure alignment and orientation for maximum signal transfer between opposing ferrule end faces.

Abstract: A managed fiber optic connector assembly formed with an optical fiber management enclosure. The optical fiber management enclosure is formed with a back body as one-piece to form an integrated fiber optic management enclosure, or fiber optic management enclosure is inserted into the back body form a two-piece enclosure. The fiber management enclosure has a plural of channels, for example, an upper channel and a lower channel that retain, separate and guide a plural of optical fibers that are accepted through a port at a distal end of the managed fiber optic connector assembly.

Abstract: An optical connector assembly having a connector housing with a first and second end. First end accepts a ferrule assembly, and second end accepts a retention assembly. There is a longitudinal bore from a distal to proximal end of connector. Bore accepts a POF optical fiber therein at distal end and fiber is inserted proximally until fiber bottoms-out at proximal end of ferrule. Retention body accepts one or more retention caps, or retention body contains at least one retention wing set to secure fiber to connector.

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.

Abstract: A fiber optic adapter for mating with a fiber optic connector includes an adapter housing. The adapter housing includes a wall and an opening that accepts the fiber optic connector. An optical alignment axis extends through the adapter housing and passes through the opening of the adapter housing. A guide is disposed on the wall of the outer housing. The guide comprises a cam surface located inward of the opening, facing toward the opening, and extending along an axis that is transverse to the optical alignment axis. The cam surface is arranged for engaging the fiber optic connector inserted into the opening along an insertion axis that is divergent from the optical alignment axis to drive the fiber optic connector substantially into alignment with the optical alignment axis as the fiber optic connector traverses the cam surface upon being pushed farther into the adapter housing.

Abstract: Optical fiber connectors and adapters are disclosed. A connector assembly includes a sleeve seal positioned near a proximal end of the connector, the seal fits over an alignment sleeve contained within an adapter. The connector may include a heat shrinkable tubing covering a distal end of the connector to prevent ingress of moisture and debris. The sleeve seal is compressed by a proximal face of a connector plug frame. The sleeve seal contains a plural of sealing or mating surfaces to prevent the ingress of moisture through the adapter opening into the plug frame housing a ferrule. The adapter further comprises a washer-seal that is placed between an adapter flange face and a module face plate that secures the adapter with connectors therein to a rack of adapters.

Abstract: A fiber array device configured to secure and align one or more optical fiber bundles as part of a main body using a fixing material. The fixing material is light cured or room temperature cured. Main body forms an angle from a first direction along a second direction, and a recess the optical bundles are laid within and in which the fixing material is applied. Each individual optical fiber is laid within a groove formed in a lid, the base portion or both the lid and the base portion. The fiber array device is secured to a printed circuit board to form a communication path between the optical fiber and electronics of the board.
