摘要：An optical transmission device includes an extractor that extracts respectiveoptical signals from optical signals multiplexed from a plurality of optical signals of
different wavelengths, a detector that detects wavelengths of the extracted respectiveoptical signals, a storage that stores the wavelengths of the detected respective opticalsignals, and a processor that is operative to derive trends in wavelength variation of therespective optical signals based on the detected respective optical signals and therespective optical signals stored in the storage, and determines that either one or bothof the extractor and the detector cause the wavelengths to be varied when the trends inwavelength variation of two or more wavelengths are the same.
