Abstract: An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.

Abstract: Connector assemblies having an adjustable polarity are described. A connector assembly having an adjustable polarity comprises a housing and a locking component configured to couple to the housing, the locking component including a compression element. The connector assembly further comprises a latch component configured to rotate around the locking component when the compression element is compressed to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position.

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: A stackable adapter having opposing ports configured to accept differing fiber optic connectors along a longitudinal axis. The stackable adapter is formed from opposing partially open sidewalls having a recess and a protrusion opposite one another near a top edge and bottom edge. Mating two stackable adapters forms a stackable adapter assembly with stackable outer sidewalls for reducing the width of an array of two stackable adapters by at least one-third over placing two standard adapter side-by-side in the panel.

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 connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

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.
