Abstract
In the wavelength division multiplexing optical transmission system according to the present invention, when setting the transmission wavelengths of the wavelength-variable optical transmitter in case of addition or expansion of the optical transmitter, each transmission wavelength is set automatically so as to match with each port wavelength of the input port in the multiplexer. Therefore, the setting workload of the optical transmitter is remarkably reduced, and occurrence of incorrect setting can be avoided. Also, with a simple and low-cost structure, the cost is restrained from increasing.
