Abstract :
Free Space Optical Communication become more and more popular due to its advantage over Radio Frequency Communication. In this paper BER and Q-factor is observed 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 Bit Rate and Divergence. If Bit rate and Divergence is increase BER will increased and Q-factor is decreased. It is observed that with Mach-Zehnder optical modulator we get a BER of 10-20 at a distance of 1.8 km with bit rate 2.5 Gbps and Q-factor 30 is achieved at a distance of 1.6 km with 2.5 Gbps bit rate.
