摘　　要：光纤通信系统作为长途通信网的主体,承载了多种类型的信息数据。光纤通信网实行带宽可变性可以动态分配带宽,既能够应对时变的用户需求,又可以精细化分配带宽资源,提高频带利用率。文章围绕密集波分系统的各种新技术的涌现和发展,使光纤通信网带宽动态可变性成为了可能。As the main body of long-distance communication network,optical fiber communication system carries many types of information data.Optical fiber communication network can dynamically allocate bandwidth by implementing bandwidth variability,which can not only cope with t ime-varying user needs,but also fi nely allocate bandwidth resources and improve band utilization.The emergence and development of various new technologies around dense wavelength division system make it possible to dynamically change the bandwidth of optical fiber communication network.

关 键 词：光纤通信 动态可变带宽 密集波分 面向用户
