This work aims to investigate the performance of Free Space Optical Communication link under average and worst rain weather conditions of India. The meteorological data related to rainfall, from 2014 to 2017, was obtained from the Indian Meteorological Department for six different locations of India, representing the inland and coastal areas. The attenuation coe cient due to rain for all the locations has been calculated using mathematical models. The performance analysis of Wavelength Division Multiplexing based Free Space Optical Communication system has been analyzed, by incorporating the attenuation due to rain for all considered locations, in terms of received power, signal to noise ratio, bit error rate and eye diagrams. The inland location of Hyderabad has given the best results in terms of above mentioned parameters as it has recorded minimum average rainfall of 2.35 mm/hr with minimum attenuation coe cient of 1.91 dB/km and can support a link range of 5.43 km, corresponding to bit error rate of order of 10 -9 under average rain weather conditions. On the other hand, the average rainfall is maximum for the coastal area of Mumbai with a value of 7.31 mm/hr, resulting in maximum attenuation coe cient of 4.08 dB/km and the maximum link range is limited to 3.48 km, corresponding to bit error rate of order of 10 -9 under average conditions of rain weather. Similarly, the inland locations of India have delivered a better link performance as compared to coastal areas under worst rain weather conditions also. So it has been concluded that the coastal areas of India have shown major degradation in the performance of the FSOC link as compared to inland locations of the country.
