摘　　要：利用光波分复用(WDM)系统,将五组不同波长的光信号组合复用并耦合到光缆信号的同一根光纤中进行传输,采用光学仿真软件OptiSystem进行光发送机,光传输链路,光接收机模块的搭建和分析。本文通过改变输出光功率,光纤传输长度和光纤的损耗系数的参数,验证系统可行性,探究其对于光纤通信系统性能的影响,得出本系统最佳输出光功率,最远传输距离,和最佳光纤损耗系数参数,建立了一个可靠性良好的光纤通信系统。该系统相对于传统的光纤通信,具有更高的灵敏度和更低的误码率,对未来光纤通信技术的发展具有深远的影响。Using the optical wavelength division multiplexing(WDM)system,five groups of optical signals with different wavelengths are combined and multiplexed and coupled into the same optical fiber of the optical cable signal for transmission.Use the optical simulation software OptiSystem to construct and analyze the optical transmitter,optical transmission link,and optical receiver module.In this paper,by changing the parameters of the output optical power,the optical fiber transmission length and the loss coefficient of the optical fiber,the feasibility of the system is verified,the influence on the performance of the optical fiber communication system is explored,the optimal output optical power,the longest transmission distance,and the optimal fiber loss coefficient parameters of the system are obtained,and a reliable optical fiber communication system is established.Compared with traditional optical fiber communication,this system has higher sensitivity and lower bit error rate,which has a profound impact on the development of optical fiber communication technology in the future.
