Simulation Investigation over 1680km WDM Transmission System Reviewing NRZ and RZ Modulation Formats
-The investigation of a 16x10Gbps WDM transmission system on 0.8nm channel spacing over 1680km optical link distance with Single Mode Fiber (SMF) is predicted. Two different modulation techniques namely NRZ and RZ are examined. It is analyzed the BER, Q values and eye opening factor for this model using two different modulation formats. The simulation results show the dominance of WDM transmission exploiting NRZ encoding technique for long-haul optical transmission system. It is found that Q penalty is 0.68dB for channel 1 and 0.24dB for channel 8 considering eye diagrams with respect to NRZ and RZ modulation formats.
