摘要

自由空间光通信(FSO)是继光纤通信之后的又一发展。本文利用OptiSystem 16软件，对FSO进行了调幅(AM)光模拟链路通信和开关键控归零(OOK-RZ)和开关键控不归零(OOK-NRZ)调制的光数字链路通信。连续波(CW)激光作为光源，采用选择性调制技术进行调制。通过增加FSO信道的距离，对发射和接收的信号进行逐步分析，得到FSO系统能在不产生误差的情况下接收发射信号的适当距离测量。

Free Space Optic communication using Optical AM, OOK-NRZ and OOK-RZ Modulation Techniques

Free space optic (FSO) communication is recent work over optical fiber communication. In this paper, optical analog link communication using Amplitude modulation (AM) and optical digital link using On-Off Keying-Return to Zero (OOK-RZ) and On-Off Keying-Non Return to Zero (OOK-NRZ) modulation for FSO has been carried out using OptiSystem 16 software. A Continuous wave (CW) Laser is used as an optical source and modulated using selective modulation techniques. The transmitted and received signal is gradually analyzed by increasing the distance of the FSO channel, to get the proper distance measurement up to which the transmitted signal can be received without any error for the FSO system.
