ABSTRACT:
First and second photoelectric converting circuits are provided to be connected to first and second input terminals of a differential amplifier, respectively. The first and second photoelectric converting circuits are optically coupled to a common optical fiber, so that first and second electric signals which are reverse in polarity are supplied to the first and second input terminals. Consequently, noise superposed, for instance, on a power supply line is supplied through the first and second photoelectric converting circuits to the first and second input terminals of the differential amplifier with the same phase as each other, so that the noises are cancelled in the differential amplifier.
