置。In an optical data highway device that includes at least one highway monitoring device and a plurality of station nodes, each of the devices is connected in a ring through a multiplexed optical transmission line and data is exchanged between arbitrary station nodes. The station node is provided with means for detecting a drop in the light level from the optical transmission line, means for notifying a highway monitoring device when detecting a drop in the light level, and means for switching the multiplexed optical transmission line. In addition, the highway monitoring device instructs a predetermined station node to switch the optical transmission line in response to a notification of a decrease in the optical level from the station node, thereby reconfiguring the loop and transmitting and receiving data. Features of optical data highway equipment.
