ABSTRACT:
In a receptacle-type module, a sleeve for receiving and holding a ferrule of a light connector has a plurality of grooves which are formed on an inner wall surface of the sleeve so as to be parallel to the ferrule insertion direction or spiral and have a crossing angle of not greater 45 degrees relative to the ferrule insertion direction. With this feature, it is possible to prevent accumulation of foreign matter or dust, with the result that the amount of variation of optical characteristics is minimized. Thus, the receptacle-type module can have high reproducibility and high reliability.
