The disclosure relates to an optical fiber connector and cable assembly that includes an optical fiber cable and an optical fiber connector, wherein the optical fiber cable has an optical fiber and a cable sheath, and a free end of the optical fiber is provided with a ferrule, and the ferrule is associated with a ferrule spring. The optical fiber connector includes a connector body and a cover; a first fixing sleeve and a second fixing sleeve, between which the cable sheath is anchored; an insert mounted at a distal end of the first fixing sleeve, having a passage for receiving a proximal section of the ferrule and supporting the ferrule spring. In a direction facing a distal end of the connector body, the cover presses a first fixing sleeve, the first fixing sleeve presses the insert, the insert presses the ferrule spring, and the ferrule spring presses the ferrule. The disclosure also relates to an optical fiber cable connection system including two optical fiber connector and cable assemblies to be connected to each other. The optical fiber connector and cable assembly may have relatively simple structure, easy assembly and reliable operation.
