Abstract
Dust storms are considered a new influence on free space optical communication (FSOC) link. It is referred to the suspended particle in the atmosphere at the desert environment. A few information about dust storms impose on us to explore the dust effect on the performance of (FSOC). This paper investigated the realization of FSO link under dust situations and take into account the effect of dust concentration. Some of the metrics used for the assessment of system including received optical power, channel capacity, signal to noise ratio (SNR), bit error rate (BER). It has been found that dust is a severe deterioration that give rise to the link decay under high concentration of dust. Moreover, we noted that the system suffers from working for the long optical link. The increase in the concentration of dust makes for low visibility, this reason leads to an increase in errors of transmitter data. Furthermore, the system can be worked with efficient channel capacity. Therefore, dust can be deemed as the decadence optical link in FSO.
