ABSTRACT:
An optical bus type communication system comprises a bus type transmission line consisting of an optical fiber, a light source provided at the one end of the bus type transmission line for sending an optical signal having a constant level to the bus type transmission line, a plurality of optical switches mounted on the bus type transmission line, and a plurality of terminal interfaces. Each terminal interface sends data by switching the corresponding optical switch so that the optical signals on the transmission line are modulated with the data.
