我们提出了一种基于轮询方案的自匹配用于无源光网络监控。每个最终用户都配备了一个光学匹配器，该匹配器仅利用特定长度的跳线和两个具有 100% 反射率的不同光纤布拉格光栅。简单且低成本的方案可以大大简化网络链路状态的最终识别处理并降低光电探测器的灵敏度。我们分析了反射脉冲之间的时域关系，并建立了评估误报率的计算模型。实验证明了该方案的可行性和时域关系分析的有效性。
We propose a self-match based on polling scheme for passive optical network monitoring. Each end-user is equipped with an optical matcher that exploits only the specific length patchcord and two different fiber Bragg gratings with 100% reflectivity. The simple and low-cost scheme can greatly simplify the final recognition processing of the network link status and reduce the sensitivity of the photodetector. We analyze the time-domain relation between reflected pulses and establish the calculation model to evaluate the false alarm rate. The feasibility of the proposed scheme and the validity of the time-domain relation analysis are experimentally demonstrated.
