Abstract :
When digitally compensating for chromatic dispersion in coherent systems, we propose to adjust the number of operations according to each lightpath requirement so as to save energy through DSP power scaling. We achieve energy savings up to 77% (resp. 57%) into the compensation stage, when considering a core network scenario at 100 (resp. 200) Gb/s.
