Performance Analysis of NRZ and RZ Modulation Schemes in Optical Fiber Link Using EDFA

Dense Wavelength Division Multiplexing (DWDM) is the current area of interest to exploit the bandwidth offered by optical fiber to enhance the data rate requirements. In the present paper analysis of DWDM system using Erbium Doped Fiber Amplifier (EDFA) is carried out in C-band. The 32-channel Wavelength Division Multiplexing (WDM) system, with a high-performanceflowrate of 10 Gbps, has been evaluated. The performance of Return to Zero (RZ) and Non-Return to Zero (NRZ) modulation formats in an optical communication system are investigated by modeling an optical fiber link using software OPTISYS V14. According to the modulated outputs, a comprehensive comparison in terms of Q factor is developed to establish the advantages and disadvantages of the code formats NRZ and RZ in short and long haul optical fiber communication system. Optimum results of Bit Error Rate (BER) and Q-factor are obtained for 60, 80 and 100km of fiber length. Pumping is discussed at 980nm and 1480nm.
