我们提出并实验证明了一个集中的PON监测方案，使用一个单一的光纤布拉格光栅的反射谱。该方案中使用的每个光纤布拉格光栅采用不同的中心反射波长或3dB反射带宽。每个光纤光栅经过宽带探测光源的探测后，产生了独特的反射谱。这些产生的反射光谱用于识别和区分分出光纤链路。通过建立相似性分析模型，解决了同一中心反射波长下不同3 dB反射带宽的波形叠加识别问题，进一步提高了网络监测能力。该方案为大容量网络，特别是终端用户距离差异较小的高密度网络提供了一种简单有效的监测解决方案。
We propose and experimentally demonstrate a centralized PON monitoring scheme using the reflection spectrum of a single fiber Bragg grating. Each fiber Bragg grating used in the scheme adopts different central reflection wavelength or 3-dB reflection bandwidth. The unique reflection spectrum is generated after each fiber Bragg grating used is interrogated by a broadband probe source. These generated reflection spectra are used to identify and distinguish the drop fiber links. The similarity analysis model is established to solve the problem of waveform superposition identification for different 3-dB reflection bandwidths with the same central reflection wavelength, which can further improve the network monitoring capacity. The proposed scheme provides a simple and effective monitoring solution for large-capacity network, especially for high-density network with small end-user distance difference.
