Optical transmission apparatus and dummy light inserting method |
摘要 |
An optical transmission apparatus includes a wavelength multiplexing unit that performs wavelength multiplexing with respect to dummy light for each channel of WDM and dummy light for each sub-band including the channels in plural; and a selecting unit that measures for each sub-band and corresponding to intensity of the channel-specific dummy light, transmission characteristics at a reception end, and according to measurement results, selects for each of the sub-bands, any one among the channel-specific dummy light and the sub-band-specific dummy light. The wavelength multiplexing unit wavelength multiplexes any of the channel-specific dummy light selected for each of the sub-bands by the selecting unit. |
