Abstract

PURPOSE:To connect many networks, by providing a function detecting an address signal to an optical fiber cable repeater between optical signal branching circuits constituting a loop. CONSTITUTION:Bus system networks 1, 2, 3 are connected via optical signal branching circuits 11-1, 11-2, 11-3, optical cables 46-1-46-3, 46-1'-46-3', and repeater circuits 51-1-51-3. The circuits 51-1-51-3 detect an address signal included in an optical signal from data terminal devices 21-1-21-5 of the networks 1-3, and when this signal is coincident with a prescribed address signal, the signal is stopped and when not coincident, a received optical signal is amplified and outputted.
