Hi everyone.
I am designing an FSO system in Optisystem.
We know that 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. With Mach-Zehnder optical modulator I got 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.
Is there a provision to get better BER and Q-factor for same parameters?
What could be the possible solutions?
Looking forward for your suggestions.
Thanks & Regards
Remo
