き（なる。The optical signal transmitted by the light emitting element is transmitted via an optical fiber, received by the light receiving element, passed through a circuit section, and converted into an electrical signal. Here, the minimum light reception level necessary for processing in the circuit section is determined by the processing circuit. Also, the transmission loss of optical fibers naturally increases as the distance increases.
