| 摘 要： | 分插复用器（ＡＤＭ）是组成同步数字传输网（ＳＤＨ／ＳＯＮＥＴ网）的基本单元，它可以同ＳＤＨ的终端复用器（ＴＭ）、同步数字交叉连接设备（ＳＤＸＣ）及网络管理设备（ＴＭＮ）等网络单元（ＮＥ）一起组成配置灵活的ＳＤＨ传输网络。光群路单元板（ＯＡＵ板）是ＡＤＭ的核心部分。本文简要介绍ＡＤＭ的功能组成与ＯＡＵ板的参考设计。

| Abstract: | AddDrop Multiplexer (ADM) is the basic unit for composing a Synchronous Digital Transport Network. A SONET/SDH network can be made up of such Network Equipments (NE) as ADM, Terminal Multiplexer (TM), Synchronous Digital Cross Connection (SDXC) and Network Management System (NMS) with much flexibility. The optical Aggregate Unit is the most important part of ADM. This paper introduce the composition of ADM and the reference design of OAU board.\= |
