Abstract :
Free Space Optical Communication become more and more popular due to its advantage over Radio Frequency Communication. In this paper performance of system is observed in form of BER and Q-factor at different parameters. It is observed that BER is increased with increase in distance and Q-factor is decreased with increase in distance. BER and Q-factor is also affected by input power. If input power is increase then signal intensity is increased and maximum signal is reached at receiver. It also affects BER and Q-factor by decreasing the value of BER and increasing Q-factor. It is observed that with Mach-Zehnder optical modulator we get a BER of 10-90 at a distance of 1.7 km with input power 6dBm and Q-factor 60 is achieved at a distance of 1.6 km with input power of SilBm.
