We selected the NRZ modulation technique over 40 Gbps Fiber Optic System Gbps. Because the transition between two codes does not return to zero in NRZ, it is not suited for high-speed
Phase modulation schemes are attracting much interest for use in ultra-fast optical communication systems because they are much less sensitive to fibre nonlinearities compared to
Optimum receiver performance relies on a balance between noise and intersymbol interference (ISI) for NRZ transmission, while for RZ reception detection noise has to be traded against filter-induced
