Abstract: Optical fiber connectors configured to allow ease of change of the connector polarity by providing lockable outer housing. In an embodiment, an optical fiber connector comprises an inner housing, at least one key configured to move along the inner housing so as to change a polarity of said optical fiber connector, and an outer housing disposed around at least a portion of the inner housing and configured to slide in a longitudinal direction so as to expose at least a portion of said at least one key, wherein the outer housing includes a flexible portion configured to lock to the inner housing so as to retain the outer housing in a pulled back position relative to the inner housing. A removable alignment key is reattached to the connector to correspond to a first or second polarity.

Abstract: Low profile optical fiber connectors comprising a ferrule, a plug frame configured to receive the ferrule, and an outer housing configured to receive the plug frame. The outer housing may be configured to protrude less than about 2 mm from one end of an adapter when the low profile optical fiber connector is inserted into the adapter. The connector may include a boot sized such that the boot protrudes from the end of the adapter by less than about 15 mm. The low profile connector does not contain a bias spring to urge the ferrule forward out of plug frae housing.

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: Reversible polarity fiber optic connectors are provided having housings at least partially surrounding first and second optical ferrules with walls above and beneath the ferrules. Positioning removable elements such as latches, removable arms, or push-pull tabs on the first wall above the ferrules yields fiber optic connectors with a first polarity type, and positioning the removable elements on the second wall beneath the ferrules yields fiber optic connectors with a second, opposite polarity type. Various engagement mechanisms are provided on either the connector housing walls or on the removable elements, or both, to assist in affixing the removable element to the connector housing.

Abstract: Fiber optic connection assemblies that may include hybrid adapters and connector assemblies are generally described. The hybrid adapter may be configured to connect a first connector type and a second connector type, the first connector type being different from the second connector type. For example, the first connector type may be a micro connector and the second connector type may be an LC connector. A connector assembly may be configured as a micro connector having a tension element configured to facilitate optimized optical performance by spring loading the ferrules while maintaining a small form factor.

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 behind-the-wall optical connector having an outer housing configured to be inserted into an adapter with a corresponding inner surface, and a latch attached to one side of housing configured to lock the connecter into an adapter opening. The latch is further configured with a locking channel and guide to accept a pull tab with a catch at one end, the pull tab releases the connector from the adapter opening when the tab is pulled rearward or away from the adapter. The ferrule assembly is inserted into a first end of the housing and when latched to the adapter, the assembly is retained in the housing without any locking structure therein.
