Advanced Monitoring Systems for Next Generation Passive Optical Networks

In the frame of this thesis, we focus on the development of simple and effective next generation passive optical network (NG-PON) monitoring schemes. We propose two transmission reflection analysis (TRA) based PON monitoring techniques, accordingly, two fast and simple montoring schemes are developped for various NG-PONs. The proposed solution was numerically studied and successfully tested in laboratory for a time- and wavelength division multiplexing (TWDM)- long reach (LR)-PON configuration for both feeder and distributed fibers monitoring. Both theoretical analyses and experimental validationsnshow that the proposed two solutions are able to monitor the PON system with a good spatial accuracy, a high detection speed and a low impact on data traffic.
