ABSTRACT:
An optical connector and splicer including an optical fiber positioning member for optical coupling of optical fibers where the coupling is assisted by at least two guide pins. The optical fiber positioning member comprises a substrate plate and a flat plate. The substrate plate has optical fiber grooves and guide pin grooved each formed at one surface thereof for positioning the one optical fibers and said guide pins, respectively. The flat plate has a flat surface confronting with the grooves surface of the substrate plate. An exposed area is formed on a part of the substrate plate where said flat plate is not joined for facilitating an insertion of the optical fibers into the optical fiber grooves. A method of the optical connector and splicer comprises the steps of: preparing a substrate plate assembly form a single wafer made of a hard and brittle material; continuously forming a predetermined pattern of optical fiber grooves and guide pin grooves on a surface of said substrate plate assembly; bonding at least one flat plate to said surface of said substrate plate assembly with an adhesive thin layer, so that optical fiber groove holes and guide pin groove holes are provided; cutting a bonded assembly into sections each having predetermined dimensions of said positioning member; and fixing the optical fibers in said optical fiber groove holes by bonding with an adhesive.
