Analysis/Simulation of Unavailability of FSO Link Due to FOG in Karachi

Now a day’s transmission of data using infrared light in free space through laser is keen interest of researchers as compared to traditional fiber optics and RF transmission due to its inherent advantages, such as low cost, easy to install and maintain high bandwidth in license free spectrum, Like other unguided media the local climate degrades the system performance of FSO system. The effect of fog on narrowband (780 nm to 850nm
