Abstract: In an ingress-protected fiber optic connector assembly, an optical fiber plug mates with a receptacle at a bulkhead adapter and an ingress-protected housing assembly couples to the bulkhead adapter to enclose the optical fiber plug. The ingress-protected housing includes an outer housing and a compressible cable seal. The outer housing is rotatable to advance the outer housing, simultaneously compressing the compressible cable seal and fastening the housing assembly to the bulkhead adapter. The outer housing can have a plurality coupling positions at which the cable seal is compressed with a different amount of compression force. A non-sealing cable clamp can transfer tension on the cable to the bulkhead adapter.

Abstract: A micro connector kit including a ferrule assembly, an optical sub-assembly (“OSA”) and a micro connector. The ferrule assembly is coupled to an optical fiber and includes a ferrule. The OSA can receive an electric signal and transmit an optical signal or receive an optical signal and transmit an electric signal. The OSA includes a receptacle sized and shaped to receive the ferrule of the ferrule assembly to form an optical connection between the ferrule assembly and the OSA. The micro connector secures the optical connection between the ferrule assembly and the OSA. The micro connector includes a micro connector housing that forms a direct, mating connection with the OSA to secure the optical connection between the ferrule assembly and the OSA. The connection is made using only a very small space, allowing more ferrule assembly and OSA connections to be made in a smaller area.

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: A very small form factor multifiber fiber optic connection system includes an adapter and mating connectors with complementary prealignment features for prealigning multifiber ferrules in the adapter to prevent guide pin stubbing. The adapter has a prealignment feature formed on at least one interior side of each individual connector port and the connectors have a complementary prealignment formation along a side wall of the connector housing assembly. Each prealignment feature slidably engages the prealignment formation of a fiber optic connector as the fiber optic connector is inserted into the individual connector port to prealign a multifiber ferrule of the fiber optic connector in the adapter.

Abstract: A new fiber optic connector provides a very small form factor with reduced size. The fiber optic connector may comprise a single-body housing having a front end and rear end in a longitudinal direction, two ferrules accommodated in the housing and protruding from the front end of the housing, a back housing positioned adjacent to the rear end of the housing, two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward, and a boot assembly connected to the rear end of the housing. The housing comprises a latch arm extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter.

Abstract: A connection system may include fiber optic connectors and an optical receptacle into which the connectors are plugged. The fiber optic connectors are constructed so that the width of the connectors is small. Eight fiber optic connectors can be received in an opening of a QSFP style transceiver.

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.
