Abstract
An optical bus transmission system wherein, even in the presence of an obstacle, a stable transmission is ensured if a plurality of transceivers are provided in the home station, or, if the subsidiary stations are equipped with a relay function and the transmission time is controlled to generate a vacant transmission time among the subsidiary stations, a more stable transmission is achieved, and, if the level of the light of the subsidiary stations is arranged to be controlled by the command information from the home station, the transmission becomes stable even when a obstacle is present.
