基于子网连接保护(SNCP)光传送网(OTN)设备光功率调测

Optical power measurement based on subnet connection protection (SNCP) optical transmission network (OTN) equipment

稳中介绍基于子网连接保护(SNCP)的光传送网(OTN)基本概念以及技术优势。针对当前传输容量需求迅猛增加而导致的带宽紧张,可以在不改造地下光缆的前提下提供传输容量。提出了在基于子网连接保护(SNCP)的网元 A、网元B、网元C、网元D四点环接线拓扑下的设备光功率调测方法,本方法可以作为各个单站光口功率计算的依据之一。

This paper introduces the basic concept and technical advantages of OTN based on SNCP.In view of the bandwidth shortage caused by the rapid increase of the current transmission capacity demand,the transmission capacity can be provided without transforming the underground optical cable.This paper presents a method of optical power measurement based on SNCP in four point ring topology of network element a,network element B,network element C and network element d.This method can be used as one of the basis of optical port power calculation of each single station.
