In this report, the effect of two main fiber optic limitations on high bit rate for 10 Gbps and 40 Gbps transmission of Dense Wavelength Division Multiplexing (DWDM) Network Systems is investigated. These are Dispersion and Nonlinearities which include chromatic dispersion, Self Phase Modulation (SPM), Cross Phase Modulation (XPM) and Four Wave Mixing (FWM). Different network layouts have been simulated to investigate them, and the results are analyzed and discussed to optimize data transmission.
