Abstract

Free space optics (FSO) system is an optical communication technology in which air or vacuum is used as medium for the transmission of signal from one place to another in the form of light propagating in free space. FSO meets the need of modern wireless communication by high speed connectivity, license free operation; long distance and high security are some of its various features which add its effectiveness. 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 and θdiv 0.5mrad the achieved values of quality factor (Q) are 13.05 and 12.38, bit error rate (BER) is 3.03*〖10〗^(-39) and 1.52*〖10〗^(-35) respectively. The paper also discusses simulation study of comparison of direct modulator laser and controlled pump laser for the proposed FSO link.
