SIMULATIVE ANALYSIS FOR THE INTEGRATION OF STARGATE NETWORK TO PASSIVE OPTICAL NETWORKS

The emergence of new bandwidth hungry applications and services impose the network upgrades of current time-division multiplexing passive optical network (TDM PONs) to their upgraded successor wavelength division multiplexing (WDM) PONs. Access network has to overcome the first/last mile bandwidth bottleneck between the high bandwidth demand at user end and high speed backbone network. Single hop WDM network based on central passive star coupler (PSC) have received a great deal of attention as promising solutions for metropolitan and local area networks which face increasing amount of traffic. This work explores the performance of a stargate network, a relatively new class of single hop network based on an Arrayed Waveguide Grating (AWG), which provide all-optical integration of Ethernet based wavelength division multiplexing passive optical networks (WDM EPONs) with metropolitan area networks. The simulation analysis revealed that the STARGATE network architecture is cost effective with minimum hop count between transmitting and receiving ends and wavelength reuses by exploiting multiple free spectral ranges (FSRs) of arrayed waveguide grating (AWG).The simulation has been performed using Optisystem V.12 software and results have been shown as eye diagrams and BER plots obtained at the receiver end.
