Abstract: A mechanical transfer ferrule is formed from a top housing and a bottom housing secured together with a plural of clips, catches and snap from a distal end of the housing portions to a proximal end of the housing portions. A plural of upper grooves formed in the upper housing and a plural of lower grooves formed in the lower housing accept a plural of optical fiber provided by a ribbon cable at a distal end of the mechanical transfer ferrule. At a proximal end of the upper housing is a pressure surface received in a pressure surface cut-out in the lower housing, where the pressure surface secures and orients the optical fiber within the channels formed by the upper and lower grooves to aid in repeated mating with a corresponding mechanical transfer ferrule and polishing the end face of the plural of optical fibers.

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 micro connector kit includes first and second ferrules and first and second micro connector ferrule housings. Each first and second micro connector ferrule housing defines a cavity sized and shaped to receive a respective one of the first and second ferrules with the first and second ferrules being disposed in closely spaced relation with the respective first or second micro connector ferrule housing when in each cavity. The first and second micro connector ferrule housings can be releasably coupled together such that the first and second ferrules form an optical connection when the first and second micro connector ferrule housings are coupled together. The first and second micro connector ferrule housings have first and second connection structure for releasably coupling the first and second micro connector housings together.

Abstract: A field installable fiber optic connector is formed without the need to splice two opposing optical fibers together. A ferrule flange assembly with one or more crimp zones secures an optical fiber therein. The assembly is secured within a plug frame housing that has a bias spring, both secured therein by an extender cap. A cable retainer with at least two wings secures the optical cable when a retainer nut is screwed onto a backpost of the extender cap.

Abstract: Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a latch component that is removably connected to the housing. The connector may furthermore include a push-pull tab removably connected to the housing and configured to move horizontally along the outer surface of housing when a biasing force is applied in at least one of a forward direction and a rearward direction. Accordingly, the push-pull tab can compress the latch component when moving horizontally along the housing, and an inverted ramp at a proximal end of the push/pull, the ramp aides in depressing the latch downward to release the connector from a receptacle.
