ABSTRACT:
A new type of optical power attenuator of the variable attenuation type. The optical connector ferrule edges are finished by polishing them at an inclination angle of seven to 12 degrees with respect to the optical axis thereof, and both ferrule edges face each other with a gap therebetween. One of the ferrule edges is fastened not so that it can be rotated whereas the other can be rotated around its optical axis. The attenuation is determined by both the inclination and gap, and it can be set stably by adjustment of the angle of the rotation around the optical axis of the ferrules.
