光纤传输特性 衰耗系数 是多模光纤和单模光纤最重要的特性参数之一，在很大程度上决定了多模和单模光纤通信的中继距离-Transmission characteristics of optical fiber attenuation

This function computes the LP guided modes of a step-index optical fiber using Matlab s "fzero" function available in the Matlab s Symbolic Toolbox. The "fzero" function uses Brent s method to find the root of a continuous function of one variable gi
