摘要：In this paper, we propose and design a passive opti- cal network using an array of fiber Bragg gratings (FBGs) for centralized monitoring of the branched op- tical networks. Further, we exploit the linear proper- ties, 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 pres- ence 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, w e envisage that the results presented in this paper would turn to be an asset in the area of passive optical network (PON).
