項記載の光固定減衰器。[Scope of Claim for Utility Model Registration] (1) In an optical fixed attenuator installed between an optical fiber connector of an optical fiber transmission line and its receptacle, an optical fiber on the connector side is connected between the light input side and the light output side. A fixed optical attenuator, characterized in that a rod-shaped body made of a translucent material and having a diameter smaller than that of the rod-shaped body is arranged along the optical transmission direction. (2) In the installed state, one end face of the rod-shaped body made of a translucent material is placed opposite the end face of the optical fiber on the connector side with a small distance between them, and the other end face of the small diameter optical fiber is in the uninstalled state. The optical fixed attenuator according to claim 1, which is arranged at a position corresponding to the end face position of the optical fiber on the connector side. (3) Claims 1 or 2 for utility model registration, in which the rod-shaped body made of a translucent material is an optical fiber.
Optical fixed attenuator as described in section.
