Abstract
An optical transmission system includes: an optical transmission device that has a plurality of optical transmitters configured to output at least one different wavelength and a multiplexer configured to multiplex wavelength lights output by the plurality of optical transmitters and output a multiplexed wavelength light; and a detection unit configured to detect each wavelength light that is branched before being fed into the multiplexer by sweeping an objective wavelength for detection, wherein, in a single sweeping, the detection unit selects and detects two or more wavelength lights with a wavelength interval that is wider than a wavelength interval of an output light of the multiplexer.
