The performance of self-configured free-space-optical transceiver algorithm is investigated. The use of multiple transmitters and receiver simultaneously with various extreme weather conditions in Malaysia and Pakistan. A self-configured-transceiver (SCT) algorithm is developed to perform better in all type of extreme weather condition. The experiment is simulated in Optisystem-14, to measure the stability of performance in the presence of extreme weather. In this simulation a continuous wave and pump-laser at 1550 and 980 nm is used simultaneously with APD and PIN diode in (SCT) respectively. The performance is measured at the distance of 30 m in foggy weather condition with attenuation of (3.83 dB/km). The pump-laser with PIN diode (−8.67 dBm) performs same as CW-laser with PIN diode (−51.18 dBm). Whereas, in the same weather condition the Pump-laser with APD (84.61 dBm) and CW-laser is (2.10 dBm). These results show that multiple transmitter and receiver in SCT algorithm improve the results compare with traditional FSO system.
