In this paper FSO link is analyzed for 650nm wavelength operation. Simulation results provide maximal link range of around 2540 meters using visible light red spectrum. The bit rate obtained for optimized link is 10Gbps. The performance of proposed link can also be improved for sustainability of communication channel in various weather conditions and is evaluated on the basic of parameter like BER, Q factor and eye diagram. For θdiv 0.2mrad the achieved values of quality factor (Q) is 13.05, bit error rate (BER) is3.03*〖10〗^(-39) . The paper also discusses simulation study of comparison of NRZ modulation and RZ modulation for the proposed FSO link.References
