guard-bands (fixed guard-band) and the case where guard-bands are selectively assigned
to the superchannels that will require less 3R as a result (optimized guard-band). Naturally,
all carriers in a superchannel must be spectrally adjacent whereas in single channel mode
they do not. However, a demand can also be partitioned into multiple … Given the influence
of regeneration on the cost of the DWDM layer, the objective of this work is to optimize the …
