Abstract:

Free space optics (FSO) has the great prospective for future communication. FSO link is a license free, secure and easily deployable and offers low bit error rate link. Over the last two decades free space optical communication (FSO) has becomes progressively interesting as an adjacent or alternative to radio
frequency communication. In this paper analysis is performed for non return to zero (NRZ) and return to zero (RZ) line codes with various operating wavelengths using APD and PIN photodiodes receivers. The study comprises the effect of atmospheric attenuation due to scattering effects for different weather conditions and observes the pointing error and received signal power at different weather conditions.
