Abstract: 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.

Abstract: Embodiments disclosed herein are directed to a fiber optic connector with that can be released from a receptacle port such as an adapter or a transceiver. The release assembly is a push/pull tab, a cable boot release and a latch controller called the release types. The fiber optic connector is field installable, and is configured to change polarity when configured with the release types.

Abstract: A fiber optic connector is spliced to an optical fiber provided by a sheathed optical fiber and an optical fiber pigtail. The connector houses a protective sleeve that secures the splice area from damage due to movement of optical fibers during connecter use. The protective sleeve retains the sheathed optical fiber at a first end and secures the protective sleeve to a distal end of a ferrule flange assembly at a second end.

Abstract: Splicing or connecting optical fibers extending from a first ferrule and a second ferrule is accomplished using heat or epoxy. Two half ferrules of differing dimensions or the same dimensions are secured together using a pair of guide pins. One of the two ferrules is biased by a spring forward and against a second ferrule to form the mechanical transfer ferrule. The mechanical transfer ferrule is secured within an inner housing of a fiber optic connector by a spring push that is secure to a distal end of the inner housing. A slidable outer housing biased forward by an elastic arm that ensures the fiber optic connector with the spliced two half ferrules is secured within an adapter port.

Abstract: A fiber optic connector having a set of opposing pins set in a recess configured to accept a corresponding spring therein. The springs are placed on either side of the fiber optic cable bundle and secured within pinkeep. The dual or outer springs help prevent rotation of the ferrule assembly during use.

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 reversible polarity fiber optic connector includes an outer housing having a front end, a rear end, and a receiving space defined between the front end and rear end; a ferrule assembly accommodated within the receiving space and configured to form an optical connection with a receptacle, the ferrule assembly including at least one ferrule protruding from the front end of the outer housing and configured to switch between a first position and second position; and a boot assembly rotatable connected to the rear end of the outer housing. When the boot assembly is rotated to an unlock position, the boot assembly is able to disconnect with the outer housing and the ferrule assembly is able to switch between the first position and second position.

Abstract: An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.
