Abstract: In this paper we present a new and gifted technology Optical wireless communication (OWC) systems. It undergoes from average optical signal power loss and random power fading due to the different atmospheric condition. For focused laser beams along direct line of sight propagation, the averages received optical signal power and Bit Error Rate (BER) as functions of the high data rates and are studied via large scale numerical simulations. In that case we evaluate the performance of OWC we consider a link of distance 500 meter, optical window 1550nm and three different atmospheric condition 10dB/Km, 40dB/Km and 60dB/Km. The VCSEL laser is used for direct line of sight communication and at the receiver side the APD is used for power reception. The NRZ – OOK modulation format is used for laser beam modulation.
Keywords: Optical Communication Link (OWC), VCSEL, APD, Bit Error Rates, Optical Received Power.
