“…Kaur and Singh [9,10] have given the method for optimization of inter-channel separation and inter-amplifier separation considering the combined effect of SRS and FWM in the presence of ASE noise to achieve maximum signal to noise ratio at low data rate i.e. 2.5 Gbps, considering Signal to Noise ratio as the deciding factor.…”

“…The two conventional limiting factors in designing optical communication systems, namely, fiber loss and dispersion, are relatively well understood, and can be easily overcome by optical amplifiers and dispersion compensation but fiber nonlinearities have not been fully analyzed and understood despite a rich collection of literature dealing with fiber nonlinearities [2][3][4][5][6][7][8][9][10]. Therefore, it is crucial to understand fiber nonlinearities and their effects on fiber-optic communication systems.…”

In this paper, Optical Dense Wavelength Division Multiplexed Systems (DWDM) employing Erbium Doped Fiber Amplifiers (EDFAs) are investigated with the main emphasis on the fiber nonlinearities like Stimulated Raman Scattering (SRS) and Four Wave Mixing (FWM). Analysis has been carried out for the calculation of the bit-error-rate (BER) considering receiver noise as well. The dependence of BER on system parameters such as system length, inter-amplifier separation and inter-channel separation has been shown graphically.

In this paper the combined impact of stimulated Raman scattering (SRS) and four-wave mixing (FWM) on the downlink channel performance of dense wavelength division multiplexed-gigabit passive optical networks (DWDM-GPONs) has been compared with the single impact of FWM via signal-tocrosstalk ratio (SXR) simulations performed on center downlink channels of 7-, 15-and 31-channel DWDM-GPON systems. Simulation results show that SRS compensates negative impacts of FWM and compensation significance enhances with increasing channel numbers and channel spacing values. At high channel spacing values of 50 GHz and 100 GHz, variation of SXR can display a strong oscillatory behavior in very short channel length variations of 0.5 km. The combined impact of SRS and FWM enhances the maximum oscillation amplitude of SXR variation with respect to the single impact of FWM at those channel spacing values. It has been observed that Raman gain exhibits an approximately linear variation with channel input powers in 0.1-5 mW range and it increases with increasing fiber lengths, channel spacing values and channel numbers. Results of this research emphasize the significant difference between the combined impact of SRS and FWM and the single impact of FWM on DWDM-GPON systems and give important hints for current DWDM-GPON implementations.

“…Kaur and Singh [15] have given the method for optimisation of interchannel separation considering the combined effect of SRS and FWM in the presence of ASE to achieve maximum SNR at low data rate i.e., 2.5 Gb/s. From the study of literature it can be concluded that attempts have been made to optimise one or another system parameter considering different nonlinearities.…”
