Claims

[Claims for Utility Model Registration] By interposing the cylindrical ferrule through which the tip of the optical fiber is inserted between the first and second plugs having different outer diameters, the ferrules of the respective plugs can be connected to each other. A diameter conversion adapter for an optical connector for optical connection, which comprises a cylindrical first ferrule part that abuts against a ferrule of a first plug, and a cylindrical second ferrule part that abuts against a ferrule of a second plug. an integrated composite ferrule, and in this composite ferrule, the outer diameter of the first ferrule portion is aligned with the outer diameter of the ferrule in the first plug, and the outer diameter of the second ferrule portion is aligned with the outer diameter of the ferrule in the first plug. An optical connector diameter conversion adapter characterized by being aligned with the outer diameter of the ferrule of the plug.
