摘要
基于ATM的无源光网络(APON)技术是实现FTTx的最佳方案。首先介绍了APON系统的构成,重点介绍其中的关键技术———上行通信中的测距、快速比特同步、突发信号收发和媒体接入控制;最后对APON的应用和发展前景做了简要的叙述。
ATM -based passive optical network(APON)technology is the best solution for FTTx.First,the architec-ture of APON system is introduced.Key technologies are analyzed,includ-ing uplink distance testing,fast bit syn-chronization,burst transceiving as well as media access control.Finally,APON application and development trends are described briefly.
