In this work we introduce the use of the per-band link control method in cascades of distributed fiber Raman amplifiers (DFRAs) for compensating power transients of WDM channels. By using two compensation channels, each one controlled by a proportional-integrative electronic control circuit and assigned to a particular signal band, the power excursion achieved in the surviving channels, in a cascade of 10 DFRAs, is reduced from 4.88 dB to 0.24 dB, when 17 out of 20 channels are added or
more » ... By adding more compensation channels, this transient protection technique can be extended to wideband DFRAs applications.
