1.OPM简介早在2000年,随着光通信行业的兴起,OPM作为一个在线监测通道光功率、中心波长及光信噪比(OSNR)等指标的功能模块已经引起人们的关注,也有相应的产品面世,但一直未能在实际系统中大规模的使用。直到2008年,随着ROADM的技术成熟,智能光网络的发展和3G网络的推广,OPM才逐渐由一个可选配件成为光网络构建中不可或缺的一部分,在实际
1. Introduction to OPM As early as 2000, with the rise of optical communications industry, OPM has attracted people’s attention as a functional module for on-line monitoring of channel optical power, center wavelength and optical signal-to-noise ratio (OSNR) The product is available but has not been able to be used on a large scale in real systems. Until 2008, with the maturity of ROADM technology, the development of intelligent optical networks and the promotion of 3G networks, OPM gradually became an indispensable part of optical network construction from an optional accessory. In practice
