Simulative Investigation of WDM-FSO Link under Different Atmospheric Conditions
Main Article Content
Abstract
Free space optics (FSO) technology has various advantages over different communication systems such as higher data rates/speed, bandwidth and capacity despite of these advantages, it has attenuation problem which can degrade the system performance. So by using Wavelength Division Multiplexing (WDM) over FSO link, the system capacity can be increased. In this paper, 8channels WDM-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, bit error rate (BER) and maximum link distance. The simulation work reports a minimum value ofBit Error Rate (BER) attained is greater or equal to 10-11 optimized link range. The optimized link range for heavy rain, light rain, heavy haze, light haze, clear and very clear sky is achieved as 4km, 10km, 16km, 50km, 150km and 190km respectively.
