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 connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

Abstract: A micro connector kit includes first and second ferrules and first and second micro connector ferrule housings. Each first and second micro connector ferrule housing defines a cavity sized and shaped to receive a respective one of the first and second ferrules with the first and second ferrules being disposed in closely spaced relation with the respective first or second micro connector ferrule housing when in each cavity. The first and second micro connector ferrule housings can be releasably coupled together such that the first and second ferrules form an optical connection when the first and second micro connector ferrule housings are coupled together. The first and second micro connector ferrule housings have first and second connection structure for releasably coupling the first and second micro connector housings together.

Abstract: A behind-the-wall optical connector an outer housing configured to be inserted into an adapter with a corresponding inner surface, a ferrule included in an annular collar to mate with a corresponding projection at an adapter opening, and a latch attached to one side of housing configured to lock the connecter into an adapter opening. The latch is further configured with a locking channel and guide to accept a pull tab with a catch at one end, the pull tab releases the connector from the adapter opening when the tab is pulled rearward or away from the adapter.

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 managed fiber optic connector assembly formed with an optical fiber management enclosure. The optical fiber management enclosure is formed with a back body as one-piece to form an integrated fiber optic management enclosure, or fiber optic management enclosure is inserted into the back body form a two-piece enclosure. The fiber management enclosure has a plural of channels, for example, an upper channel and a lower channel that retain, separate and guide a plural of optical fibers that are accepted through a port at a distal end of the managed fiber optic connector assembly.

Abstract: A boot assembly having a boot body with passageway molded from a proximal to distal end of the body. The passageway accepts a repositioning device made of a malleable material such as metal that retains its shape under internal forces of the boot assembly. The boot assembly further comprises one or more cables for fiber optics or power. Bending the flexible boot assembly from a first position to a second position, the flexible boot assembly retains the second position without returning to the first position under the resilient material of the boot.

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: 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 push on (MPO) optical connector includes a housing supporting a ferrule body. The ferrule body forms an optical connection with a second MPO optical connector. 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. The distal ends of the optical fibers are coated with an anti-reflective material.
