Abstract:
A pumping light source unit for Raman amplification includes at least one pumping light source that outputs a first pumping light covering a current amplification band; at least one additional pumping light source that outputs a second pumping light covering an amplification band to be extended; and a setting control unit that controls a setting for a gain of an entire amplification band by resetting outputs of the first pumping light and the second pumping light. The pumping light source unit has a function of extending the amplification band in a stepwise manner.
