An optical transmission apparatus includes a network, a plurality of transponders, a monitor, a multiplexer, and demultiplexer. The plurality of transponders connected with the network, each of the plurality of transponders having a response transfer processing unit for communicating between the other transponders via the network, the plurality of transponders categorized a first transponder and a second transponder. The monitor connected with each of the transponder units, respectively, the monitor monitoring the plurality of transponders and sending a first request and a second request to the plurality of transponders. The first transponder responds an answer to the monitor via the network when the first transponder receives the first request. The second transponder responds an answer to the monitor instead of the first transponder via the network when the first transponder receives the second request.
