Design & investigation of 32x10 GBPS DWDM-FSO Link under Different Weather condition

Gurpreet Kaur, Harmeet Singh


Due to growing demand of high speed, data rate and bandwidth has led to the emergence of free space optics (FSO) technology. It has various advantages such as high data rates, bandwidth and capacity.FSO system requires free space as channel. Attenuation offered by the channel can degrade the system performance. So by using Wavelength Division Multiplexing (WDM) over FSO link, the system capacity can be increased more effectively. In this paper, 32 channels DWDM-FSO system has been designed and analyzed in worst weather conditions at 1550 nm wavelength using NRZ modulation. The performance of the simulated system has been investigated in terms of quality (Q) factor, data rate and maximum link distance. The simulation work shows that high data rate upto 10Gbps with maximum link range has been achieved at Bit Error Rate (BER) 10-10
I. INTRODUCTION under different weather conditions. The maximum link range up to 513 km at data rate of 10Gbps is achieved for very clear weather condition.
