1. A fiber optical connector assembly comprising:
an optical fiber cable including a cable jacket and optical fibers within the cable jacket;
an optical fiber ferrule terminating at least one of the optical fibers of the optical fiber cable;
a connector housing receiving the optical fiber ferrule and comprising a backpost;
a crimp tube assembly secured to the back post, the crimp tube assembly comprising a first end portion and a second end portion spaced apart along a longitudinal axis, the crimp tube assembly defining a first crimp zone, a second crimp zone, and a third crimp zone spaced apart along the longitudinal axis, the second crimp zone being located on one side of the first crimp zone along the longitudinal axis of the crimp tube assembly, the third crimp zone being located on a longitudinally opposite side of the second crimp zone from the first crimp zone, the first crimp zone crimped onto the backpost, the second crimp zone crimped onto the cable jacket of the cable, and the third crimp zone crimped onto the cable jacket of the cable, the crimp tube assembly further comprising an access port extending radially with respect to the longitudinal axis at a location spaced apart between the second crimp zone and the third crimp zone along the longitudinal axis, the crimp tube assembly defining a space extending radially between the cable jacket and the crimp tube assembly and longitudinally from the second crimp zone to the third crimp zone; and
cured epoxy located in the space, the epoxy having been received into the space through the access port.
