Abstract
Abstract An optical network system having a ring-type network, a bus-type network, and a plurality of stations connecting the ring-type network to the bus-type network. Each station has a plurality of internal buses, and a plurality of transmission-reception processing stations each corresponding to the internal buses. The transmission-reception processing sections independently perform the transmission of data between the ring-type network and the bus-type network.
