Abstract
PURPOSE:To obtain a logical sum by selecting some of output of logic circuits simultaneously by providing plural light emitting parts to emit light with different wavelength, and plural light receiving parts with the different light receiving sensitivity of a frequency chatacteristic. CONSTITUTION:Output signals from the logic circuits 107-109 connected to the light emitting parts 104-106 having different frequency characteristics are transmitted to an optical fiber 101 from each of the light emitting parts 104-106 after being converted to light with different wavelength. At the light receiving parts 102 and 103, the frequency characteristic with high light receiving sensitivity is attached on the light with the wavelength corresponding to a desired signal so as to obtain the logical sum of the signals, and no influence is given on the light with another wavelength. In such a way, it is possible to receive the light of plural desired signals by one Iight receiving part, and to obtain the logical sum selectively by using the light.
