Broadcasting and Multicasting in All Optical Packets Routing TWDM PON

Requirements for future bandwidth demand from access network keep changing, in order to support more streaming video on multicasting and broadcasting packet, a novel architecture of dynamic Multiwavelength Time Wavelength Division Multiplexing Passive Optical Network (TWDM PON) system using multicasting Cross Gain Multiplexing (XGM) and all optical packet routing (AOPR) module in optical line terminal (OLT) is presented. The multicasting XGM technique was implemented by using Semiconductor Optical Amplifier (SOA). The study proved that the single PON port/card was able to generate multicast and broadcast packet up to more than 512 users using 8 PON link over existing PON infrastructure. The architecture is designed to support flexible dynamic wavelength allocation based on bandwidth demand from each customer from 10Gbps single channel to multiple channels of 10Gbps using multiple PON port. This paper is concluded with an analysis and discussion on the simulation of physical performance of gain saturation effect in pre amplification device using SOA components, the number of multicasting wavelength affecting the BER, the Q factor and quality of the signal in the downstream proposed system Keywords-component; WDM PON, TWDM PON, Cross Gain Modulation, Multicasting, Broadcasting.
