Abstract
Abstract An optical fiber connector assembly and method for splicing a broken fiber optic cable is described which includes first and second elements joinable in a mated condition along respective first and second mating surfaces; first and second grooves in the mating surfaces extending essentially the lengths of the surfaces and defining a channel of preselected size through the assembly in the mated condition for receiving the cable sheath within the assembly in the mated condition; a cavity in one of the mating surfaces for receiving the abutting optical fiber ends; an adhesive for holding the optical fiber ends in abutting relationship; an ambient temperature curing material sealing the mating surfaces from moisture and foreign substances and fixing the abutting optical fiber ends within the assembly; and a plurality of screws for assembling the elements.
