An optical processor 100, includes the first optical processing unit 100a and the second optical processing unit 100b which are optically connected with each other. The first optical processing unit 100a includes an EA modulator 110, an electric signal processing device 112, which is electrically connected with the EA modulator 110, through the first and second relays 116, and 118, and a sinusoidal voltage generator 114. The second optical processing unit 100b includes a light detection means 130, the second electric signal processing device 132, which is electrically connected with the light detection means 130, through the third relay 134. In the optical processor 100, as constituted above, there can be realized the optical modulation and light detection by the EA modulator as well as the light detection by the light detection means. Consequently, it becomes possible to effectively receive the alternating multiplexed optical signal without wasting the energy thereof.
