Migration to the next generation optical access networks using hybrid WDM/TDM-PON

Abstract

Due to the rapid growth of Internet and multimedia services, broadband fiber access technologies, such as Passive Optical Networks (PONs), come to the forefront of the research field. Network service providers mostly deploy Time Division Multiplexed (TDM)-PON everywhere in the world. In order to mitigate the future demand, researchers have investigated some nextgeneration PON systems, such as Wavelength Division Multiplexed (WDM)-PON and hybrid WDM/TDM-PONs. In this report, we propose the architecture of a self-restored hybrid WDM/TDM-PON. Due to the restorable capacity of the architecture, the availability of the PON system increases. Furthermore, the proposed architecture is a cost effective solution compared to the existing restorable PON architectures. Finally, we analyzed the power budget and signal quality of the proposed architecture, which proves the applicability of the proposed architecture to the access networks. © 2011 ACADEMY PUBLISHER.
