Abstract
In a disconnectable low-loss optical connector for optical fiber light guides, the fiber is precisely located in the body of the connector form in a molding die cavity. The portion of the cavity that forms the mating surface of the molded connector body corresponds to a frustum of a cone whose axis is a reference point for determining the exact location of the fiber. The fiber is placed in a sleeve-like member to form a subassembly around which the connector body is molded. One end of the member has a port located in the tip of the frustum of the molding cavity and aids in the precise formation of the mating surface. When the molding cavity is filled to form the molded connector body, gas pockets which form and produce voids in the molding material are accepted in a flow of filler material and prevented from interfering with the formation of the mating surface. The fiber which protrudes out of the tip of the mating surface is then cut and polished to form the junction end. If a shortened, modified sleeve-like member is used instead of the first-mentioned member during the molding process, the fiber may be terminated at a device encapsulated during the connector formation. This device may be either a light source or light detector so that the connector includes a means of interfacing conventional electronic circuitry with the light wave milieu.
