摘要
In one aspect, a WDM signal is assigned to a number of sub-bands with the channel spacing being correspondingly enlarged in each sub-band. The spectral hole burning is hereby essentially reduced, since this effect is restricted to the adjacent channels. The complete WDM signal is first pre-amplified before being divided into sub-bands.
