| 摘 要： | 由于千兆无源光网络系统中的上行光信号采用高速突发模式,故对其特性的检测是实现实时光层监测的难点.详细分析了上行光信号的传输特性、帧开销及噪声模型.并在此基础上,设计了一种检测方案,该方案通过高阻抗的前置放大器将信号引出,不影响原系统的正常工作,从而满足了实时检测的需要;通过峰值检波电路将高频突发信号降为低频进行处理,大...

| Abstract: | It is difficult to realize real-time power detection as the upstream signal of gigabit passive optical network(GPON) system is high-speed burst mode.Based on the analysis of the upstream signal transmission characteristics,the frame overhead,and the noise model,a new detection method is presented.This method raises the signal to the original system with pre-through high-impedance amplifier,which does not affect the performance of the original system.High-frequency burst signal will be down converted for pro... |
