摘要
ATM无源光网络 (PON)中上行方向采用时分复用 (TDM)方式 ,光线路终端 (OLT)的接收机工作在突发模式 .本文提出了一种基于关键字检测来提取突发同步时钟的简单方法 ,模拟分析表明此方法性能可靠 .若采用高速ECL器件 ,此方法亦可用于超级无源光网络 (Super PON)及其它高速TDMA系统中 .
The Time Division Multiplexing (TDM) is adopted in passive optical network based on Asynchronous Transfer Mode (ATM),so a receiver of the Optical Line Terminal (OLT) operates on the burst mode.A simple method of burst synchronization based on a keyword detection is presented.Simulation and analysis indicate that the configuration is reliable.It can be also used in super PON and other TDMA systems for burst clock recovery with resent commercial ECL circuits.
