Multi-Beam Free-Space Optical Link to Mitigation of Rain Attenuation

Farouk Kh. Shaker and Mazin Ali A. Ali


Free-Space optical (FSO) link is an optical communication technology that uses light or laser as the carrier diffuses into free space to transfer data information between the transmitter and the receiver through the air channel. In this paper, a dual transmitters and receivers with multi-beam technique were designed to Study the effects of rain attenuation on the system to be used through FSO during the rainy weather. FSO model system was designed and simulated using OptiSystem7.0 software. The results analysis of FSO link within (1.6 - 3.9 km) ranges according to a Charbonneau model for rain attenuation. The transmitting data with NRZ modulation was designed and analysis of the performance System efficiency parameters such as bit error rate (BER) and Q. Factor for different optical links. The results of the simulation showed that the received signal power decreases and the bit error rate is increasing when the rain rate is increasing.
