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.

The body holds one or more dust shutter plate, a corresponding bridge member, and an actuator that opens the dust shutter or moves the dust shutter plate from a closed position covering an opening in the alignment sleeve holder to an open position, so the connector ferrule can be accepted into an opening at one end of the alignment sleeve holder.

Abstract: Optical fiber connectors and adapters are disclosed. A connector assembly includes a sleeve seal positioned near a proximal end of the connector, the seal fits over an alignment sleeve contained within an adapter. The connector may include a heat shrinkable tubing covering a distal end of the connector to prevent ingress of moisture and debris. The sleeve seal is compressed by a proximal face of a connector plug frame. The sleeve seal contains a plural of sealing or mating surfaces to prevent the ingress of moisture through the adapter opening into the plug frame housing a ferrule. The adapter further comprises a washer-seal that is placed between an adapter flange face and a module face plate that secures the adapter with connectors therein to a rack of adapters.

Abstract: A fiber optic connector having a push/pull tab wherein the push/pull tab travel is limited by an internal stop to release a connector from a receptacle, and the push/pull tab is releasably secured from connector. The push/pull tab has a plural of securing protrusions that secure the tab to the connector housing.

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: 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 fiber optic connector with a rotatable connection member for converting the connector from a first polarity to a second polarity, and a manipulator assembly comprising a tab member and a locking member movable between a locked position and an unlocked position, the manipulator assembly being coupled to the connection member such that the manipulator assembly and the connection member rotate conjointly about the axis of rotation, and when in locked position connector polarity cannot be changed.

Abstract: A reversible polarity fiber optic connector includes an outer housing including a polarity key for coupling the outer housing to a fiber optic receptacle in only one orientation. A ferrule assembly is received in the outer housing in a first position corresponding to a first polarity of the fiber optic connector and in a second position corresponding to a second polarity of the fiber optic connector. The ferrule assembly forms an optical connection with the fiber optic receptacle. A boot assembly is releasably connected to the outer housing to enable the ferrule assembly to be inserted into and removed from the outer housing. The boot assembly includes a rotor rotatable between locked and release positions. The rotor includes a blocking portion to block disconnection of the boot assembly with the outer housing in the locked position and to permit disconnection of the boot assembly with the outer housing in the release position.

Abstract: A fiber optic connector has a housing including separately formed housing portions configured to be connected to each other to cooperatively define an enclosure. A first of the housing portions has a latch formed integrally with the first housing portion. A fiber optic ferrule is located in the enclosure of the housing. The housing portions each define a back post element which together define a back post of the housing configured for securing a cable to the housing.

The ferrule body includes a connection end having a distal end face arranged to face the second MPO optical connector when the ferrule body forms the optical connection with the second MPO optical connector. The connection end of the ferrule body defines a recess extending proximally into the ferrule body from the distal end face. A plurality of optical fibers are received in the ferrule body. Distal ends of the optical fibers are adjacent to a proximal end of the recess such that the distal ends of the optical fibers are spaced apart from the second MPO optical connector when the ferrule body forms an optical connection with the second MPO optical connector.

In some embodiments, the reduced-profile connection components may be used with conventional connection components. For example a reduced-profile connector may use a conventional MT ferrule to establish a connection within a conventional MPO adapter.
