ABSTRACT The present invention relates generally to fiber optics and, more particularly, to a fiber optic connec- tor assembly for a fiber optic cable having one or more single optical fibers therein. It is highly desirable to provide for crimping of fiber optic cables for termination to contacts or connector assemblies as is commonly done with electrical cables. However, if an optic cable is crimped like an electrical cable, the one or more single fibers in the cable will be over-stressed and damaged. In a fiber optic cable, the crimping must be done to the strength members which surround the optical fibers. According to the present invention, a connector body is provided for receiving the optical fibers of the cable and has a rear end portion over which the strength member of the cable is positionable The rear end portion of the connector body is provided with one or more annular crimp receiving grooves. A ferrule member is positionable over the grooved rear end portion of the connector body for crimping the strength member between the ferrule member and the connector body. The ferrule member is crimped to have one or more crimping ribs which are nested in the grooves of the connector body clamping the strength member therebetween. The included grooves of the connector body are smaller than the ribs of the ferrule member so as to increase the number of crimping areas between the connector body and the ferrule member.
