摘　　要：本文主要介绍了随着宽带网走入我们的生活,现已建成的SDH骨干网正承受巨大的负荷,在不久的将来,将必然难以满足日益增长的通信需求。为此只有建立起一套具有高带宽、大容量、低时延、拓扑结构灵活的传输系统才能够解决上述问题,这便引入了我们所研究的课题即长距离大容量DWDM传输系统。本篇论文主要介绍了DWDM传输系统的基本知识点和DWDM系统在传输过程中所运用到的关键技术介绍。通过本文的阐述旨在说明长距离大容量DWDM传输系统在现代宽带通信中的特点以及其能够在日常生产中被应用的可行性。This paper describes the network as broadband into our lives, has now completed the SDH backbone network is under heavy load, in the near future, will inevitably be difficult to meet the growing communications needs.This is only to establish a set of high bandwidth, large capacity, low latency, flexible transmission system topology in order to solve these problems, which have introduced the subject of our study that long-distance high-capacity DWDM transmission system. This paper introduces three DWDM transmission system on the basics of points , respectively, the WDM technology is a basic introduction , the basic technology introduction and DWDM DWDM transmission system used in the introduction to the key technology.Produced by the purpose of this paper is to demonstrate the long-distance high-capacity DWDM transmission system in the modem characteristics of broadband communications and it can be applied in daily production feasibility
