Abstract

Along with the development of the Fiber-to-the-Home (FTTH) networks, the Passive Optical Network (PON) is largely studied. PON technology is known as optical access network technology that uses fiber optic and passive devices to connect service providers and end users. Some models for deploying PON have been proposed. In this paper we focus on mesh and star topology for hybrid WDM-TDM PON. We propose three design methods for the two models and compare them to each other in order to see the advantage of mesh topolgy with links between AWGs. These methods are also compared with the solution in [11]. The results show that the proposed methods gains better performance and the use of link between AWGs allows saving a noticeable fiber amount.
