Abstract: An optical connector assembly a first structure and a second structure, the two structures secured together using a retention structure to form a hybrid assembly. The retention structure uses a slot apex located in a slot channel for securing at least one latch pin of a coupling nut to an adapter housing forming the ingress protected connector without the use of a bias spring. The hybrid assembly is designed to resist water or debris ingress, and may eliminate the use of a bias force to further resist separating the hybrid assembly.

Abstract: An optical fiber connector assembly comprises at least one connector having a latching arm for coupling to an adapter, and a remote release tab having a protrusion configured to cooperate with the adapter to depress said latching arm when the remote release tab is pulled relative to the adapter. The optical fiber connector assembly may further be configured to allow reversing its polarity.

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: An optical connector assembly having a connector housing with a first and second end. First end accepts a ferrule assembly, and second end accepts a retention assembly. There is a longitudinal bore from a distal to proximal end of connector. Bore accepts a POF optical fiber therein at distal end and fiber is inserted proximally until fiber bottoms-out at proximal end of ferrule. Retention body accepts one or more retention caps, or retention body contains at least one retention wing set to secure fiber to connector.

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: Fiber optic connection assemblies that may include hybrid adapters and connector assemblies are generally described. The hybrid adapter may be configured to connect a first connector type and a second connector type, the first connector type being different from the second connector type. For example, the first connector type may be a micro connector and the second connector type may be an LC connector. A connector assembly may be configured as a micro connector having a tension element configured to facilitate optimized optical performance by spring loading the ferrules while maintaining a small form factor.

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.
