The performance of a STARGATE network, which provides all-optical integration of Ethernet based WDM PONs with metropolitan area networks, has been extensively studied in this research. This network provides transparent connections at wavelength and sub-wavelength granularity. The network efficiency has been improved by using single hop star network and spatially reusing wavelengths by exploiting multiple free spectral ranges (FSRs) of arrayed waveguide grating (AWG). The simulation has been performed in Optsim^TM and results have been shown as eye diagrams and BER plots obtained at the receiver end.
