摘要
为了提高学生的学习兴趣,帮助学生理解、掌握知识点,提升光纤通信课程的教学效果,将OptiSystem软件引入光纤通信课堂教学。该文以光纤传输特性部分的教学内容为例,针对光纤的损耗、色散和非线性效应三项光纤的传输特性,搭建OptiSystem仿真模型,演示光纤的传输特性对光纤中传输信号的影响,进而分析对光纤通信系统性能的影响。通过仿真演示,使学生更直观地理解光信号在光纤中传输时的时域、频域变化特征,掌握光纤传输特性对光纤通信系统的影响机理。
In order to improve students'interest in learning,help students understand and master knowledge points,and improve the teaching effect of Fiber-optic Communications,OptiSystem software is introduced to the classroom teaching of Fiber-optic Communications.Taking the teaching content of fiber-optic transmission characteristics as an example,aiming at three fiber-optic transmission characteristics:the loss,dispersion and nonlinear effect of optical fibers,this paper builds the OptiSystem simulation model to demonstrate the impact of fiber-optic transmission characteristics on transmission signals in optical fibers,and then analyze the impact on the performance of the fiber-optic communication system.Through the simulation demo,students can more intuitively understand the time-domain and frequency-domain variation characteristics of optical signals when they are transmitted in optical fibers,and master the influence mechanism of fiber-optic transmission characteristics on the fiber-optic communication system.
