Abstract

In this paper, the hybrid optical amplifier composed of single erbium doped fiber amplifier and a Raman amplifier is proposed for wavelength division multiplexed system and also investigates the impact of reduced channel spacing. The performance has been evaluated in terms of gain and noise figure. Gain and noise figure are important characteristics of the optical amplifier to evaluate the performance. There are various parameters on which the gain spectrum of EDFA and Raman amplifier depends. The effort has been made to optimize these parameters by simulating the system of 16 channels in Opti system software. In this paper the length, pumping wavelength, pumping power of EDFA/Raman is optimized. After the analysis the reduction in gain is about 2.7dB and the noise figure is about6.86dB

Keywords- EDFA, Raman amplifier, HOA, WDM, Gain, Gain flatness and Noise figure
