基于Optisystem的单模光纤WDM系统性能仿真

Simulation and Analysis for System Performance of SMF WDM Based on Optisystem

利用Optisystem实现了单模光纤波分复用(WDM)通信系统。在发送端,产生了四路复用的WDM信号,信道采用单模光纤及光放大器,接收端采用光电二极管。利用光谱显示模块显示了关键节点的光谱,利用眼图模块显示了接收端恢复的电信号的眼图。实验表明,建立的单模光纤通信系统具有良好的可靠性,Optisystem非常适合光纤通信系统课程实验。

Single-mode fiber wavelength division multiplexing （WDM） communication system is Optisystem. On the sender, a four-way muhiplex WDM signal is produced. Then, the WDM signal simulated by is transmitted through the single-mode optical fiber （SMF） and optical amplifiers. On the reeeiver,photodiode is used to de- tect the signals. The spectrum are displayed at key nodes by Optical Spectrum Analyzer, and the eye diagram of recovered electrical signal are showed by BER Analyzer at the receiver end. Simulation results show that the designed single-mode optical fiber communication system owns well reliability, and Optisystem is ideal for opti- cal fiber communication systems experimental course.
