A fiber optic adapter assembly reduced in size from a SFP footprint to a SC footprint to accommodate a first fiber optic connector on a first side within one or more ports, and a second fiber optic connector on a second side within one or more ports. The first fiber optic connector is a duplex fiber optic connector with an overall length of about 50 mm and the second fiber optic connector is a behind-the-wall connector with an overall length of about 15 mm thereby reducing the overall length of a connector and adapter assembly for increasing optical fiber density.

Fiber optic adapter assembly

A multi-fiber, fiber optic connector may include a reversible keying arrangement for determining the orientation for plugging the connector into an adapter to thereby allow for a change in polarity of the connection to be made on site. The connector housing may be configured to engage with a removable key that may be engaged with the housing in at least two different locations to provide the plug-in orientation, or the housing may have slidably displaceable keys movable between multiple positions on the housing.

Optical fiber connector with changeable polarity

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 is attached to at least one side of housing configured to lock the connecter into an adapter opening. A backbody, an integrated backbody or an external clip retains the ferrule assembly with a ferrule, biased forward toward a proximal end of the connector housing.

Behind-the-wall optical connector and assembly of the same

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.

Ultra-small form factor optical connector having dual alignment keys

A small form factor 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, a pair a resilient latches and corresponding recess for the resilient latch, 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 a receptacle hook and a housing with an opening that accommodates the receptacle hook in a flexed position as the optical connector makes connection with the mating receptacle by introducing the receptacle hook into an optical receptacle hook recess.

Small form factor fiber optic connector with resilient latching mechanism for securing within a hook-less receptacle

An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer housing, ferrules, a cable boot and one or more polarity keys. The keys are configured to change connector polarity from a first to a second polarity. A corresponding adapter with one or more slots within an adapter wall on opposing sides sized and shaped to accept a single or dual keyed polarity changeable connector.

Ultra-small form factor optical connectors with polarity change and method of use

A multi-fiber, fiber optic connector is interchangeable between a male connector and a female connector by including a pin retainer having a releasable retention device configured to lock the pins in place within the retainer. The retention device may be opened, for example, with a release tool, to free the retention pins for removal of the pins. A method for switching a connector between a male connector configuration and a female connector configuration may be possible as a result of the releasable retention configuration.

Optical fiber connector with changeable gender

An integral fan-out connector assembly for fiber optic cables includes a connector housing that provides an integrated fan-out housing and connection adapter. The fan-out connector housing may be configured with a variety of cable adapters, and may be installed as a 'plug and play' type solution where it will be ready to accept a feed cable for use when needed.

Ingress protected fan-out connector and adapter assembly

An adapter based connector polarity changer is described. A hook insert is placed into an adapter receptacle at a first end or second, and is removable with a removal tool. A hook insert may be permanently placed into an adapter receptacle. The hook insert oriented in the receptacle in a first position and with a first mating structure interconnects with corresponding connector second mating structure to configure the connector in a first polarity, and the hook insert removed and oriented in a second position with the first mating structure interconnects with corresponding connector second mating structure to configure the connector in a second polarity.
