摘要
There is provided in an optical amplifier device used for a system in which a power transfer takes place from comparatively short wavelength signal to a comparatively long wavelength signal. The device includes an amplifier stage coupled to an optical transmission medium, a monitor monitoring a status of a first band; and a pump light source unit supplying at least one first pump light to the optical transmission medium on the basis of the status of the first band monitored, so that the above at least one first pump light supplies additional power to longer wavelength channels related to the status of the first band.
