Technical Examples

A transmission wavelength band in an optical transmission line is divided into a plurality of sub-bands and signal lights or an ASE dummy light is disposed per sub-band as a unit. The optical power of the ASE dummy light in each sub-band is controlled so as to realize the gain profile at a full implementation in the optical transmission line. While new signal lights are being added, the optical power of whole ASE dummy lights or the optical power of the ASE dummy lights in sub-bands adjacent to the sub-band in which the new signal lights are to be added is controlled while increasing the optical power of the new signal lights so that the transmission characteristics of the existing signal lights are not affected by the signal addition.
