Abstract: A fiber optic connector having a ferrule that forms an optical connection with another fiber optic connector. An outer housing supports the ferrule and has a front end portion and a longitudinal centerline axis. The front end portion includes a front end face with a portion of the ferrule being forward of the front end face. The front end portion includes a protector that is shaped and arranged to protect the ferrule. The protector is arranged so that the fiber optic connector and another fiber optic connector of identical construction can, starting in the same orientation, be mated together by rotating said other fiber optic connector 180° about an axis perpendicular to the longitudinal centerline axis, aligning the longitudinal centerline axes and moving the fiber optic connectors along the longitudinal centerline axes until the fiber optic connectors are mated to form the optical connection.

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: Various embodiments disclosed herein are directed to an optical fiber connector. The optical fiber connector comprises at least one ferrule, at least one ferrule spring, a connector housing for holding at least one ferrule and at least one ferrule spring such that at least one ferrule spring is loaded to urge the at least one ferrule forward. The connector housing comprises an upper wall portion, the upper wall portion comprising a recess running lengthwise. The optical fiber connector further comprises a remote release comprising a front portion slidably received in the recess, and the remote release is configured to be pulled backward in relation to the connector housing whereby the front portion slides in the recess for releasing the optical fiber connector from a mating adapter.

Abstract: Connector assemblies having an adjustable polarity are described. A connector assembly having an adjustable polarity comprises a housing and a locking component configured to couple to the housing, the locking component including a compression element. The connector assembly further comprises a latch component configured to rotate around the locking component when the compression element is compressed to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position.

Abstract: 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.

Abstract: 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.

Abstract: A micro connector kit including a ferrule assembly, an optical sub-assembly (“OSA”) and a micro connector. The ferrule assembly is coupled to an optical fiber and includes a ferrule. The OSA can receive an electric signal and transmit an optical signal or receive an optical signal and transmit an electric signal. The OSA includes a receptacle sized and shaped to receive the ferrule of the ferrule assembly to form an optical connection between the ferrule assembly and the OSA. The micro connector secures the optical connection between the ferrule assembly and the OSA. The micro connector includes a micro connector housing that forms a direct, mating connection with the OSA to secure the optical connection between the ferrule assembly and the OSA. The connection is made using only a very small space, allowing more ferrule assembly and OSA connections to be made in a smaller area.

Abstract: An optical fiber connector with a connector housing that holds a ferrule includes a retractable shutter having a shutter plate and a shutter actuator. The shutter actuator is slidably connected to the connector housing for movement relative to the connector housing between a front position and a rear position. The shutter actuator is configured to engage the mating interface as the optical fiber connector is plugged into the mating interface whereby the shutter actuator moves relative to the connector housing from the front position to the back position. The shutter plate is connected to the shutter actuator such that the shutter actuator is configured to drive the shutter plate to move between an extended position and a retracted position. In the extended position, the shutter plate is located to shield the ferrule. In the retracted position, the shutter plate is located expose the ferrule.

Abstract: 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.
