  • Publication number: 20170212316
    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.

  • Patent number: 9618703
    Abstract: Various connector housings for securing an optical cable, as well as methods of use and manufacture thereof are disclosed. A single-piece unitary connector housing body may include a first opening formed in a first end of the housing body, a second opening formed in a second end of the housing body, a bore through the housing body extending from the first opening to the second opening, and a back post surrounding the second opening. The first opening may be configured to receive a terminating optical cable and the second opening may be configured to receive a fiber optic cable. The back post may extend from the second opening in a longitudinal direction and may include a plurality of protrusions thereon. A length of the back post may have a concave shape.

  • Patent number: 9612406
    Abstract: An optical fiber connector comprises a frame and a ferrule connectable together. The frame has a key insert inside an interior passage of the frame for mating with the ferrule. The ferrule has a flange configured to mate with the key insert. The flange includes a number of V-grooves, and the key insert has the same number of tips for mating with the V-grooves. For each of two sides of an individual V-groove, at least a portion thereof forms a substantially-seamless contact with a part of an outer surface of an individual tip during mating. Hence, the individual tip is prevented from making a motion in a direction parallel to flange, thereby resisting an undesired angular displacement between the connector and an optical fiber therein to occur due to an accidental rotational force applied to the connector after the frame and the ferrule are connected.

  • Publication number: 20170059783
    Abstract: Communication device connection assemblies are described. The sealable connection assemblies are configured to provide water-tight connections for various data transmission elements, including cables, network devices, and computing devices. The connection assemblies may be used for various data transmission protocols, such as fiber optic connections. A compression element of the connection assembly may be configured to engage and compress a sealing element against a communication cable extending through the sealable connection assembly when a tension element is coupled to the inner body, thereby forming a seal between the sealable element and the communication cable. The connection assemblies may include a retainer body configured to form a grip or retention force with a communication cable sufficient to reduce and/or eliminate any forces on the communication cable (i.e.
