摘要
正值疫情期间,网络教育得到了越来越广泛的关注,而实验教学一直是网络教育的短板.通过设计一种基于Labview的光纤通信虚拟实验平台,既可实现线上的实验教学,也可对接硬件进行软硬结合实验项目操作.设备库可提供的设备包括:示波器、光波分复用器和编码器;通过网络实现的实验课程有:半导体激光器P-I特性测试实验、波分复用器插入损耗和光串扰测试实验、信道编码实验.程序平台封装后可发给学生练习,也可以上传到虚拟实验室平台共享.
Nowadays,online education has got a lot of attentions.Therefore,experimental teaching has always been the short board of online education.In this paper,a virtual experiment platform of optical fiber communication based on LabVIEW is designed.The experiment platform can realize online experiment teaching,and can also connect hardware and other software to operate the experiment project.The equipment from equipment library can provide oscilloscope,optical wavelength division multiplexer and encoder.What is more,this Experimental course that can be realized by network include“P-I characteristic test experiment of semiconductor laser”,“insertion loss and optical crosstalk test experiment of wavelength division multiplexer”and“channel coding experiment”.After the program platform is encapsulated,it can be sent to students for practice or uploaded to the virtual laboratory platform for sharing.
