OTN技术与组网应用

Technology and network application of OTN

首先介绍了OTN(optical transport network,光传送网)的概念,OTN主要技术中的数字封装技术与ROADM技术,以及OTN的4种典型设备类型。提出了基于OTN的智能光网络将为大颗粒宽带业务的传送提供非常理想的解决方案。随后,重点分析论述了如何依据《光传送网(OTN)网络总体技术要求》在国干/省干光传送网,以及城域/本地传送网2级网络中应用OTN进行组网,并提出了若干具有实用价值的工程建议。

This paper introduces the concepts of OTN（optical transport network）, its main technology——digital packaging technology and ROADM technology, and four typical equipment types of OTN. This paper points out that it is a very ideal solution to base on the OTN intelligent optical network. Then, this paper mainly discusses and analyzes how to, according to the Optical transport network （OTN） network overall technical requirement , build a network with OTN in the stem and local optical transmission network. Finally, it puts forward some practical engineering suggestions.
