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 fiber optic ferrule adapter for mating a multi-fiber optic ferrule and a multi-fiber optic connector includes a holder having a cavity where a multi-fiber optic ferrule is held therein, and a receptacle housing with an opening that allows the insertion of a fiber optic connector. The holder has a top opening for receiving the ferrule into its cavity; and two protrusions, which are respectively protruded from each interior side walls of the holder, for latching the ferrule in place inside the cavity. The holder includes a groove recessed on the interior walls of the cavity for catching a ridge on the ferrule so as to prevent any longitudinal movement of the ferrule inside the cavity. The cavity may include a slope next to an interface between the cavity and receptacle housing for allowing the sliding in-and-out of the ferrule at an angle to the top of the holder opening.

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.

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.
