Multi Parameter Gain Optimization of Raman Fiber Amplifier for Dense Wavelength Division Multiplexed Systems

Sonak Saini, Simranjit Singh

In this paper, various parameters of the Raman Fiber Amplifier are optimized for DWDM system at 0.2 nm channel spacing. The various system parameters attained optimum value to give gain value targeted at 20dB for each of the 100 channels. The multi stage approach adopted in this work results in providing maximum gain (above 15dB) for the optimized system parameters i.e. for pump power nearly equal to 600mW, signal power lies between -4 to -5dBm, pump wavelength equals to 1460nm and Raman fiber length is approximately 25Km.
