Abstract: An optical fiber connector can terminate a plurality of optical fiber cables, each with a jacket encasing at least one optical fiber and a strength element. A connector housing has a back post. The optical fibers of the plurality of optical fiber cables extend into the connector housing through the back post. A single crimp ring crimps the strength members of the plurality of optical fiber cables onto the back post. In a method of terminating a plurality of optical fiber cables, the cables are inserted through a single crimp ring, optical fibers of each of the cables are terminated in a multifiber ferrule, the cables are loaded into a back body of a connector housing, and strength members of the cables are crimped onto a back post using a single crimp ring.

Abstract: An optical fiber array module that can accommodate variations in diameters of the optical fibers in the fiber array within anticipated tolerance, to accurately and securely retain the optical fibers in grooves in the module without using any solder interface or epoxy interface between the optical fibers and the supporting components. The fiber array module of the present invention relies on elasto-plastic interfaces for mechanical deformation, as opposed to solder reflow or epoxy curing, to accommodate variations in diameters of the optical fibers in the fiber array as supported in grooves between a substrate and a cover.

Abstract: A fiber optic connector terminates a drop cable. A connector housing can include a back post where the drop cable to enters the housing. A cable clamp insert is least partially received in the back post. The cable clamp insert defines a passage for receiving the drop cable. A crimp ring is crimped onto the back post to secure the cable clamp insert to the housing and clamp the cable clamp insert onto the drop cable. Fiber optic connectors can also have a cable clamp insert and a cable clamp retainer that couples to the rear end portion of the housing whereby the cable clamp retainer pushes the cable clamp insert forward in the housing and applies an increasing force to create a tight connection between the housing and the cable clamp insert.

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.
