摘要
随着宽带光纤通信网的发展,副载波复用(SCM)技术再次引起人们极大的兴趣并得到迅速发展。本文介绍当前国际上 SCM 发展的情况及其应用前景,阐述 SCM 的基本原理,并重点论述模拟的 SCM 技术中最重要的理论问题——光源的非线性及光纤色散引起的谐波失真及交调失真.
Accompanied by the development of wideband communication networks, the interest in Subcarrier Multiplexed(SCM)lightwave systems has been renewed. These systems have been developing rapidly nowadays.This paper reviews recent progress and applications of SCM,describes the fundamental principles,and gives an analysis of the most important problem of SCM,the harmonic and intermodu- lation distortions.
