摘要
通过全数值计算方法,建立了光通信原理教学实验的可视化仿真模型。文中详细描述了光源、光纤链路、光探测及判决单元的建模原理和求解方法。利用以上模型和方法对40Gb/s单信道传输系统进行了仿真实验研究,演示效果直观形象,所得结果与实验室获得的曲线和数据相吻合。
Visualized simulation models of the teaching experimentation for optical communication are established based on all digital algorithm. The modeling principle and solving methods of the components of the optical device, such as optical source, optical fiber, photodiode and error discriminator are described in detail. The simulation for 40 Gb/s optical transmission system with single channel is conducted by using these methods. The simulation experiments make the ＇whole optical communication process become a view image, and the results conform to the data and curves in the laboratory.
