Abstract

Optical wireless communication (OWC) systems suffer from average optical signal power loss and random power fading due to the different atmospheric condition. In this paper, we propose a model for free space optical link for link distance of 500 meters and the results of this paper show the Power of the system at different Bit Rates (1Gbps to 3.5 Gbps) using three different atmospheric attenuation 10dB/Km, 40dB/km and 60dB/km. The optical wavelength (window) used for simulation is 1550nm which give the best performance as compare to other window. VCSEL is used as a transmitter because it has a reasonable, nominal average power level of several milliwatts (mw) of output at high-speed operation and high reliability numbers for mean time between failures (MTBF). The NRZ OOK is modulation format which is used here for Laser beam modulation. Different graphs of the average Received optical Power vs. Bit Rate using three atmospheric attenuations of the Free Space Optical link are obtained.
