全光通信网中的光分/插复用器

Optical add/drop multiplexers (OADM) in all optical communication Networks

在对现有的各类光分/插复用器(OADM)进行总结和比较的基础上,按结构特点将其归纳为5类基本形式,即分波器+波长交换单元+合波器型,波长光栅路由器(WGR)型,声光可调谐滤波器(AOTF)型,解复用器/复用器型和耦合单元+滤波单元+合波器型。论述了各类OADM的工作原理、结构、性能特点、技术水平及相应的关键技术,为发展相关技术、开发OADM产品、设计具有分/插复用功能的波分复用系统提供了依据和参考。

Available OADM(Optical Add/Drop Multiplexer) are summarized and compared currently . In the schemes of their structures, all of them are classified to 5 types: OADM using division multiplexing element, wavelength switching element and multiplexer,OADM using WGR(Wavelength Grating Router),OADM using AOTF(Acoustic Optical Tunable Filter),OADM using DMUX/MUX(Demultiplexer/Multiplexer),and OADM using coupling element, filtering element and multiplexer. the operational principles, configurations, characteristics, technical level and key technologies of OADMs are generally described. Providing basis and references is aimed for growing related technologies, developing OADM products and designing WDM system based on OADM.
