ABSTRACT:
An optical-signal/electric-signal converting device communications system for a communications system that establishes communications using electric and optical signals. The converting device converts an electric transmission signal into an optical transmission signal and an optical transmission signal into an electric transmission signal. The converting device includes an electric signal receiving circuit for receiving the electric transmission signal transmitted from the host computer of the communications system through an electric transmission line, and a modulating circuit for modulating the electric signal sent from the electric signal receiving circuit into a pulse signal having pulses of a smaller width. The converting device also includes an optical signal receiving circuit for receiving the optical transmission signal from the optical transmission line of the system and converting the received signal into an electric signal using a light-receiving element, and a demodulation circuit for demodulating the electric signal received from the optical signal receiving circuit into a pulse signal having pulses of a larger width.
