摘要

自由空间光通信由于其相对于射频通信的优势而越来越受到人们的欢迎。本文对不同参数下的误码率和q因子进行了观测。BER随距离的增加而增加，q因子随距离的增加而减小。误码率和q因子也受比特率和散度的影响。当比特率和散度增大时，误码率增大，q因子减小。使用马赫-曾德光调制器，在1.8 km距离和2.5 Gbps比特率下的误码率为10-20，在1.6 km距离和2.5 Gbps比特率下的q因子为30。

Design of free space optical communication link with Mach-Zehnder optical modulator for long distance

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.
