  • Publication number: 20200408998
    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.

  • Publication number: 20200393626
    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.

  • Publication number: 20200241216
    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.

  • Publication number: 20200142133
    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.

  • Publication number: 20200116950
    Abstract: An outdoor rated assembly is configured to blind mate opposing fiber optic connectors. An outdoor rated adapter has a first non-outdoor rated fiber optic connector and an outdoor rated connector has a second non-outdoor rated fiber optic connector. The opposing connector and adapter are mated to form an outdoor rated assembly to protect the two internal fiber optic connectors from moisture and debris. The outdoor rated assembly has a safety spring assembly to prevent the outdoor connector components from separating and to support a push/pull attachment and release of the outdoor connector from the outdoor adapter.
