Method of producing a receptacle-type optical connector

摘要

In a receptacle-type optical connector to be connected to a plug-type optical connector connected to an optical fiber terminated by the use of a ferrule, use is made of a base shell, a front shell, and an intermediate shell which is interposed between the base shell and the front shell. The base shell has a core coupling portion for coupling a core of the optical fiber. The front shell has an opening which is shaped in conformity with a plug shape of the plug-type optical connector. The intermediate shell is partly fitted to the base shell. The intermediate shell has a cylindrical protrusion which is shaped in conformity with the ferrule and which is inserted into the opening.
