1. A fiber optic cable assembly comprising:
a fiber optic cable comprising an optical fiber, strength members and a cable jacket; and
a connector assembly comprising:
a connector body comprising a first end, a second end, a body passageway extending from the first end to the second end, and at least one body aperture at the second end;
a crimp ring comprising a first end, a second end, a crimp ring passageway extending from the first end to the second end, and at least one crimp ring aperture at the second end, wherein the first end has a smaller diameter than the second end;
a crimp body comprising a first end, a second end, a crimp body passageway extending between the first end and the second end, and one or more crimp features; and
at least one locking element;
wherein:
the fiber optic cable is disposed within the crimp body passageway, the crimp ring passageway, and the body passageway;
the crimp body is crimped to the cable jacket such that the strength members wrap around an outer surface of the cable jacket and are disposed between the crimp body and the cable jacket;
the second end of the crimp ring is crimped to the crimp body such that at least a portion of the second end of the crimp ring is disposed within the one or more crimp features;
the first end of the crimp ring is disposed within the body passageway; and
the at least one locking element is disposed within the at least one body aperture and the at least one crimp ring aperture to secure the crimp ring to the connector body.
