A first light reflection surface () and a second light reflection surface () are formed on a lower half of a mirror block () in a state that these light reflection surfaces (), () make 90 degrees therebetween. A first light reflection surface () and a second light reflection surface () are also formed on an upper half of the mirror block () in a state that these light reflection surfaces (), () make 90 degrees therebetween. A third light reflection surface () and a fourth light reflection surface () are formed between the first light reflection surface () and the second light reflection surface () such that these light reflection surfaces (), () make 90 degrees therebetween. According to this optical switch, by changing a region which reflects the light between the upper half and the lower half of the mirror block (), the coupling relationship between an input optical fiber and an output optical fiber can be changed over.

Optical switch

Two mirrors () and () making an angle of 90 degrees are formed on a front face of a mirror member (). An optical fiber for input () and an optical fiber for output () are held in a fiber array () with a predetermined interval, and an emission lens () and an injection lens () are provided on a front face of the fiber array () in a way that they are opposed to end faces of the optical fiber for input () and the optical fiber for output () respectively. According to the variable optical attenuator, when the mirror member () is straightly moved by an actuator (), light attenuation can be varied thereby.

Variable optical attenuator

The present invention provides an optical switch that is provided with a plurality of output side optical transmission means; at least one input side optical transmission means; reflecting meanswhich moves to be positioned with respect to any one of the output side optical transmission meansand reflects an optical signal to the input side optical transmission means; and driving meanswhich moves the reflecting meansto each of the output side optical transmission means
