Abstract

We propose a flexible architecture of WDM-PON in which unicast, multicast and broadcast data is transmitted based on a novel scheme of using sidebands as carrier. We here transmit one unicast data, one multicast data and two broadcast data transmission to each ONU. With the help of single frequency reflection capacity of FBG and cyclic wavelength distribution property of the AWG a unicast/multicast data and broadcast data is transmitted to each ONU. Simulation with 10 Gbps downstream channel, 10 Gbps broadcast channel and 2.5 Gbps upstream transmission is demonstrated with acceptable performance. In the proposed architecture DI is used to separate optical carrier and sideband carrier. Carrier reuse scheme is used and therefore the ONUs are colourless.
