Comparative Analysis of AWG Demultiplexer and Chirped FBG Based Demultiplexer in WDM PON Network
In Wavelength Division Multiplexing based Passive Optical Network (WDM-PON), multiple wavelength used to separate Optical Network Unit (ONU). Which actually increase the capacity of PON .WDM process can be dense and ultra-dense depending on channel spacing. In this paper, the authors compare performance of Array Waveguide Grating DEMUltipleXer (AWG DEMUX) and Fiber Bragg Grating based DEMUltipleXer (FBG DEMUX) in dense and ultra-dense WDM at the data rate of 2.5gbps. Optical fiber length used is 10km. The maximum and minimum Q factor is compare and discussed. All the simulation was performed in optisystem 12.0.
