    摘要: In a transmission apparatus, a plurality of optical transceivers respectively generates optical signals. A plurality of transponders generates a plurality of optical signals to be multiplexed as a WDM signal from among a plurality of optical signals generated by the plurality of optical transceivers. An optical switch circuit is provided between the plurality of optical transceivers and the plurality of transponders and it switches the plurality of paths of the optical signals between them. The priorities of a plurality of optical signals to be multiplexed as a WDM signal are set in a management table. A detector detects communication conditions of the respective optical signals that are multiplexed as the received WDM signal. A control circuit switches the paths in the optical switch circuit on the basis of the priorities set by the management table when a fault is detected by the detector.

    摘要: An optical transmission device includes a wavelength multiplexing/demultiplexing unit, a plurality of transponders, an optical switch unit and a controller. The controller includes a table in which a plurality of items at least including priority order, a transmission label, a receiving label and a receiving label expected value correspond to the respective transponders. And the controller rewrites the transmission label of the transponder corresponding to the client device of the lower priority order than the priority order of the client device connected to the transponder of the irregular input, upon the optical signal provided by the wavelength multiplexing/demultiplexing unit to one of the transponders being irregular, and controls the label-changed transponder for which the transmission label has been rewritten so that the label-changed transponder provides the wavelength multiplexing/demultiplexing unit with the optical signal including the rewritten transmission label.
