The utility model provides an optical fiber connector and an optical cable which is provided with such an optical fiber connector. The optical fiber connector is installed on the optical cable whose optical fibers are covered by an external sheath and can restrain characteristic deterioration caused by external force. The utility model provides an optical fiber connector which comprises an insert core which remains on an optical fiber exposed at the front end of the optical cable, and an optical cable fixing assembly which is relatively moveably connected with the insert core and is used to fixed the outer sheath of the optical cable.
