Abstract: A connector that includes an outer housing having an assembly channel with a stopping step on an inner wall of thereof and an optical beam expanding module assembled with the assembly channel of the outer housing. The optical beam expanding module includes a rear seat, formed with a snap ring groove, in which a C-shaped snap ring is fitted. A cable having a strengthening element is fixed on a rear end portion of the rear seat. When the cable of the optical beam expanding module is pulled outwardly, the C-shaped snap ring abuts against the stopping step, so that a pulling force exerted on the cable is transferred to the outer housing through the strengthening element of the cable, instead of being transferred to an optical fiber of the cable, thus preventing the optoelectronic coupling end faces of the connector from being separated.

Abstract: An optical beam expanding module that has a housing, a ferrule mounted in the housing, a cable extending into the housing, an optical fiber of the cable being received in an inner bore of the ferrule; and an optical lens mounted in the housing at a front end surface of the ferrule for expanding the diameter of a light beam output from the optical fiber. The optical beam expanding module is adapted to be assembled as a single component in any one of assembly channels in mounting bodies of different connectors. There is provided a standardized optical beam expanding module being adapted to be applied to different beam expanding connectors.

Abstract: An optical fiber connector includes: a plug assembly holding an optical fiber ribbon. The optical fiber ribbon includes bare fibers with ground end faces. The plug assembly includes a precision guiding device and a fixing device. The precision guiding device positions the bare fibers, the fixing device holds the optical fiber ribbon, and the precision guiding device and the fixing device are detachably connected to each other.
