摘　　要：作为全光通信网的核心设备的光分插复用器(OADM),对全光网的传输能力、组网方式、关键性能都具有重要影响。本文首先在引言部分介绍光分插复用器产生的背景及分插复用器的发展阶段,之后详细阐述了光分插复用器的基本原理、基本要求。在此基础上,本文探讨了光分插复用器的分类及结构。在此部分,分析了以下几种光分插复用器:阵列波导光栅型OADM、采用声光可调谐滤波器的OADM、波导一光栅型OADM、光纤—光栅型OADM。接着,本文分析了OADM在WDM全光网络及OCDMA全光网络中的应用。最后,文章阐述了OADM技术与产品现状及发展趋势。As the core equipment of AON, OADM has great influence on the transmit ability and network originating of AON. The introduction will introduce the background and development of OADM, and then the paper will analyze the theory and requirements of OADM. When this paper explains the category and structure of OADM, it will analyze several kinds of OADM： AWG OADM, AOTF OADM, WG OADM and Fiber Grating OADM. After that, the paper will analyze the applications of OADM in WDM and OCDAM. Finally, we will introduce the OADM products and predict the development of OADM.
