Performance Analysis of Resilient FTTH Architecture with Protection Mechanism

Abstract

Fiber-To-The-Home [FTTH] is an alternate technology for broadband access networks. Passive optical network (PON) is considered the most promising solution due to the relatively low deployment cost. Current time division multiplexing [TDM] PON architectures are economically feasible, are band limited. The WDM PONs currently available offers enough bandwidth for the present and also for future multimedia broadband services. The purpose of this paper is to simulate resilient access network architecture with a cable route protection function based on hybrid wavelength division multiplexing and time division multiplexing passive optical network (WDM/TDM-PON) systems. Hybrid WDM-TDM PON combines the advanced features of both TDM PON and WDM PON. The reuse of existing optical fiber cable networks allows the introduction of duplicate routes for the shared portions of PONs by using a few optical fiber cables with simple structures. In this work, the hybrid WDM/TDM PON based Ladder network is simulated and the transmission characteristics evaluated. Simulation is done by using Optsim ver.5.3.
