A review of XDMA-WDM-PON for Next Generation Optical Access Networks

Hybrid Wavelength Division Multiplexing-Passive Optical Networks (XDMA-WDM-PON) seems to be the solution to tackle the requirements for optical access networks of the future. This article presents the trending for Next Generation Optical Access Networks (NG-OAN). In this work the requirements for optical access networks of the future are summarized in order to compare several XDMA-WDM-PON proposed solutions. Time Division Multiple Access (TDMA), Optical Code Division Multiple Access (OCDMA) and Orthogonal Frequency Division Multiple Access (OFDMA) covers the main requirements for future Passive Optical Networks. The results demonstrate that the future optical access networks will be supported by OFDM-WDM-PON architectures.
