Impact of detuning between signal wavelength and MUX/DEMUX filter passband in WDM systems was numerically studied for 50 GHz-spaced 42.7 Gbit/s RZ and CS-RZ si
A numerical simulation shows that by using electronic equalizers 1 bit/s/Hz spectral efficiency can be attained with the same signal quality as a 0.8 bit/s/Hz
