چکیده
In this paper, a 16 channel 25 Gbps DWDM optical network is simulated and analyzed for 120 km using dispersion compensating fiber. The system is operated on -10dBm of Input Power. NRZ-DPSK modulation format is used for transmission under symmetrical compensation schemes. Group velocity and third order dispersion are compensated to improve the Q-factor. Impact of Third Order Dispersion as well as Four Wave Mixing is observed on variable channel spacing such as 50 GHz, 100 GHz and 200 GHz. It is observed that stability of Q-Factor is better in case of 200 GHz channel spacing when effect of dispersion and four wave mixing is considered. Index Terms Differential Phase Shift Keying (DPSK), Dense Wavelength Division Multiplexing (DWDM), Dispersion Compensating Fiber(DCF), Group Velocity Dispersion (GVD), Third Order Dispersion (TOD), Four Wave Mixing (FWM)

Four Wave Mixing (FWM) is the parameter which restricts the transmission distance and bandwidth of optical communication systems. There are various factors which influence FWM, such as channel input power, spacing between channels, dispersion of fiber, operating wavelength and refractive index etc. The nonlinear effects tend to manifest themselves when optical power is very high and become impo...
