Hi Koll,
Systems that use WDM technique as a multiple access or modulation technique also launch their signal containing all the WDM channels (after being multiplexed on transmission side) into the same fiber. So EDFA and DCF can be used in the same way as they were used before (with regard to the center frequency of the fiber and channels frequencies).
Regards
