A Simple and Cost Effective Ring-Based Local Access C/DWDM-PON Architecture for Supporting a Truly Shared LAN Capability

This work proposes a simple and cost effective local access WDM-PON architecture that combines the salient features of both traditional static WDM-PON (i.e., dedicated connectivity to all subscribers with bit rate and protocol transparencies, guaranteed QoS, and high security) and dynamic WDM-PON (i.e., efficiently utilizing network resources via dynamic wavelength allocation/sharing among end users). Specifically, this paper proposes and devises a novel ring-based local access WDM-PON architecture that efficiently supports dynamic allocation of wavelengths /timeslots and sharing traffic as well as a truly shared LAN capability among PON end users.
