Experimental Analysis of Optical Coherent Communication System in India Through Atmospheric Turbulence

Free Space Optical FSO communication is the transmission of optical signals through the atmosphere. This technology promises high wireless data rates, highly secured transmission, license-free operation and immunity to electro- magnetic interference. However, FSO reliability is decreased considerably by atmospheric conditions. In this paper, we characterize the Ghanaian atmospheric channel for FSO communication based on visibility statistic. We use Kruse's model to estimate atmospheric attenuation in India. The probability of outage on an FSO link is computed to determine the availability of the link. Our results show atmospheric attenuation as high as 150.95dB km and 128.2316dB km in the 850nm and 1550nm transmission window respectively. The average atmospheric attenuation in India for 850nm and 1550 nm wavelengths is below 2dB km. The Probability of encountering higher attenuation condition is low.
