Evolution and application of OTN and PTN technologies in metropolitan area network
摘要
本文侧重光传送技术层面阐述。伴随用户宽带接入速率不断提高
3G无线网络带宽需求不断提高
未来城域网既要为用户提供高速率光口接入
同时又要满足无线接入带宽需求
因此未来的城域网络将形成混合组网模式
除传统波分、SDH、MSTP技术外
还将引入OTN、PTN等技术。
Abstract
This article focuses on aspects of optical transmission technology.With the subscriber broadband access rates continue to increase
the 3G wireless network bandwidth demand increases
the future metropolitan area network is to provide users with high rate optical access
as well as wireless access bandwidth demand
therefore the future metropolitan area network will form a hybrid network model
