本文分析了波分复用光传送网中光通路层 (OCh)的管理需求 ;研究了两种 OCh开销传送技术 :副载波调制结合光监控信道 (OSC)开销传送技术和 OCh帧结构开销传送技术 ,分析对比了两种技术的优缺点 ,研究了 OCh帧结构中光通路层开销具体字节定义 ;提出了采用OCh帧结构开销传送技术后光网络的分层详细结构 .
This paper analyzes the management requirements of optical channel layer (OCh) in WDM optical transport network. Two OCh overhead transmission technologies are studied: subcarrier modulation combined with optical supervisory channel (OSC) overhead transmission and OCh frame overhead transmission , Analyzes the advantages and disadvantages of the two technologies, and studies the definition of the specific byte of the optical path layer overhead in the OCh frame structure; and proposes the layered detailed structure of the optical network after adopting OCh frame overhead transmission technology.
