This paper intends to design anarti cial model of WDM Optical Network in respect of length, pump power and simple free space optical link which is designed and analysis of several FSO (Free-space optical communication) factors such as Bit Error Rate (BER), Q factor and received power have been measured with regard to the variants in the beam divergence and attenuation. The Simulation process of the System has been done using Optic simulation software to achieve gain enhancement and decrease noise factor of Erbium Doped Fiber Ampli er (EDFA) through optimized ber length and pump power. This workfocused to construct arti cial design and analyses of 16 channels WDM system using EDFA and the in uence of irregular atmospheric Motions on the link performance has been inspected by uctuating beam divergence, atmospheric disturbances and modulation format at the bit rate of 10 Gb/s. As slicing in WDM schemes, in the transmitter channel with the frequency of 1558nm and chip spacing 0.4nm, power value is equal to + 23.5dBm, whereas the optical power meter plus can be used to predict the output power in the form of NRZ modulation, while the input power is produced with a help of CW laser, the gain level has been enriched from 1564nm to 1558nm wavelength band with bit rate of 10GbpS.This system is prepared by using Optic simulation software version 7.

“…The main rawback of this technology is the impact of weather conditions [10][11][12] such as fog, haze, rain and scintillation on the efficiency of the FSO system condition especially in long distance transmission. A number of studies have reported that the range of FSO links operating in the temperate and tropical regions to be limited by fog and heavy rainfall respectively.…”

Weather severity has unfavorable effect on FSO transmission performance. The impact could result in poor quality of transmission and communication failure. This paper presents the analysis using multiple free space optic channels with amplification to mitigate haze attenuation. The visibility is progressively reduced due to the attenuation effects, causing the bit error rate to increase. Three designs of FSO system are proposed in this research as they are simulated and analysed thoroughly using Optisys software. The achieved result shows improved performance for Design 3, as the minimum BER achieved is 10<sup>-127</sup> when the power received is -26 dBm, and maximum Q-factor of 23.6 at the aperture diameter of 40 cm. It is proved to improve the system efficiently in low visibility condition compared to Design 1 and Design 2. It clearly has shown the superior capabilities of Design 3 to intercept and mitigate the atmospheric attenuation in haze condition as the power loss during transmission also reduced significantly.
