Abstract:
Abstract FSO communication system use Free Space as a communication channel, where free space introducing several effect on FSO communication system mainly atmospheric attenuation effects. The attenuation offered by different atmospheric conditions can degrade the system performance. By using appropriate optical amplifier, the system’s performance can be enhanced. WDM over FSO link can increased the information carrying capacity of the system. Hybrid amplifier (EDFA + SOA) is used to overcome the effect of attenuation. In this paper, 32channel WDM-FSO system is simulated at bit rates 5Gb/s & 10Gb/s under different weather conditions using NRZ modulation technique. The Performance of WDM-FSO system is investigated in terms of Bit Error Rate (BER) and Q-factor. The simulation results shows that, the maximum link range of 434km is achieved at data rate 5Gbps and 412km at data rate 10Gbps for very clear weather conditions & 6.2 km & 5 km at 5Gb/s & 10Gb/s respectively under heavy rain condition. Keywords: APD (Avalanche photodiode), FSO, BER (Bit Error Rate), Atmospheric attenuation, WDM (Wavelength division multiplexing), Hybrid amplifier.
