する、光固定減衰器。 A fixed optical attenuator installed between a bayonet-type connector plug of an optical fiber transmission line and its receptacle, and a transparent attenuator with a diameter smaller than that of the optical fiber of the transmission line between the light input side and the light output side. A ferrule for holding the optical rod-shaped body is integrally constructed with a connecting member for connecting to the connector plug, and a connecting member for connecting to the receptacle is attached to the ferrule so as to be slidable along the light transmission direction, and the receptacle A fixed optical attenuator, characterized in that a connecting member with the connector plug is biased by a spring toward the connecting member with the connector plug with respect to the ferrule.
