Abstract

In this paper, we propose and design a passive optical network using an array of fiber Bragg gratings (FBGs) for centralized monitoring of the branched optical networks. Further, we exploit the linear properties, namely, reflection and transmission spectra of FBGs for identifying the fiber fault. Besides, we also verify the quality of the downstream signals (1490 nm and 1550 nm) through the well-known eye-diagrams through the spectrum analyzer. We find that the quality of downstream signals remains same even in the presence of monitoring signal and the passive element FBG. Thus, these numerical results corroborate that the monitoring signal and passive element (FBG) do not affect the quality of the downstream signals. Thus, we envisage that the results presented in this paper would turn to be an asset in the area of passive optical network (PON).

测试一个使用光纤布拉格光栅阵列的无源光网络实时监控系统
在本文中,我们提出并设计了一种使用光纤布拉格光栅阵列(fbg)来集中监控分支光网络的无源光网络。此外,我们利用光纤光栅的线性特性,即反射和透射光谱来识别光纤故障。此外,我们还通过频谱分析仪通过众所周知的眼图验证下游信号(1490 nm和1550 nm)的质量。我们发现,即使在监测信号和无源元件光纤光栅存在的情况下,下游信号的质量仍然保持不变。因此,这些数值结果证实了监测信号和无源元件(FBG)不影响下游信号的质量。因此,我们设想本文提出的结果将成为无源光网络(PON)领域的一项资产。
