Abstract
An apparatus/system and a method for optical fiber two-way communication, which enables highly reliable transmission at all times in order to carry out communication at a high transmission speed when an optical fiber or a combination of optical fibers not assumed are used. A signal is transmitted with a predetermined pattern corresponding to each of a plurality of different signal transmission speeds from the signal transmitter of a first terminal to the signal receiver of a second terminal. It is then compared by the signal receiver of the second terminal with a signal of the predetermined pattern. A signal transmission speed is detected which enables transmission and reception on the basis of a signal position where the signal received by the signal receiver of the second terminal and the signal of the predetermined pattern do not coincide with each other.
