A free-space passively star-coupled optical data bus uses uniform uncollimated transmission light communicating data among a plurality of transmitter and receiver paired transceiver nodes of respective communication subsystems for communicating data from one transmitting node simultaneously to each of all of the remaining receiving nodes, the data bus being defined by a transmission volume having peripheral optical ports for optically interfacing the transceivers nodes to the free-space communication transmission medium having a distribution means to distribute the light and provide a variety of data bus configurations each supported by protocol addressing and optical modulation for connectorless communications for improved reliability and reduced costs especially well-suited for conference room, office, and spacecraft applications.
