1. An optical fiber connector assembly comprising:
an optical fiber plug configured for terminating an optical fiber cable and for mating with a receptacle at a bulkhead adapter; and
a rugged housing assembly configured to couple to the bulkhead adapter and enclose the optical fiber plug mated with the receptacle, the rugged housing assembly comprising a housing configured to mate with the bulkhead adapter, a cable seal configured to be coupled to the optical fiber cable and seal an interface between the housing and the optical fiber cable, and a non-sealing cable clamp configured to clamp onto the optical fiber cable such that movement of the optical fiber cable in relation to the cable clamp is inhibited, the cable clamp configured to be housed within the housing and interface with the housing such that, when the optical fiber plug is mated with the receptacle and the housing is coupled to the bulkhead adapter, tension on the cable is transferred via the cable clamp to the bulkhead adapter and transfer of tension to the optical fiber plug and receptacle is inhibited,
wherein the cable clamp comprises a first keying feature for keying the cable clamp in relation to the housing to inhibit relative rotation between the cable clamp and the housing.
