“光纤通信”课程是通信工程专业学生的一门必修专业基础课,其中光纤作为光纤通信的重要传输介质,光纤的传输原理、传输特性的分析是“光纤通信”课程中主要的组成部分之一[1,2]。影响光纤通信系统传输的主要因素有色散和损耗,这些因素都取决于传输介质光纤的传输特性,光作为光纤通信的载波,其工作频率范围也取决于光纤的传输特性,因此,要全面掌握光纤通信系统的传输原理及其相关应用,光纤的传输原理、传输特性以及以光纤为基础的光纤器件是“光纤通信”这门课程的重要知识点。光纤作为重要的传输介质,在实际通信应用中都选择单模光纤,可有效地提高光纤传输容量和中继传输距离,最大限度地避免模式色散和模式损耗。
传统的光纤传输原理的分析方法是基于射线光学分析和波动方程分析法,波动方程分析法是在基于麦克斯韦方……
