摘要
光放大器的应用极大地促进了波分复用系统的发展,但光放大器缺少电接入手段,对其监控只能依赖额外的光波道提供监控信息通道。文章阐述了设计光监控信道时对波长的选择考虑及相应的性能要求,并通过福建电力通信网的设备实例,介绍了光监控信道的构成、技术参数、接线方式及所完成的功能。
The application of optical amplifier dramatically promotes the development of WDM system. Additional wavelength is needed to provide monitoring information due to lack of electrical access in optical amplifier site. This paper introduces the consideration of wavelength selection and required function in designing optical supervisory channel, then presents actual equipment with technical specification, wiring diagram and facility, which used in Fujian electrical communication network.
