Abstract
An optical communication system includes a single master machine, a plurality of slave machines, and an optical adapter for optically communicating between the master machine and the slave machines. The optical adapter comprises a receiving unit, an amplifier, and an optical projector consisting of a concave mirror. The receiving unit receives optical information from either the master machine or the slave machines. The amplifier means amplifies the optical information. The concave mirror reflects or propagates the optical information of the master machine or the slave machines toward the slave machines or the master machine, respectively.
