We propose a new architecture of dynamic time-wavelength division multiplexing-passive optical network (TWDM-PON) system\nthat employs integrated all-optical packet routing (AOPR) module using 4? Ã?â?? 10Gbps downstream signal to support 20 km fiber\ntransmission. This module has been designed to support high speed L2 aggregation and routing in the physical layer PON system\nby using multicasting cross-gain modulation (XGM) to route packet from any PON port to multiple PON links. Meanwhile, the\nfixed wavelength optical line terminal (OLT) transmitter with wavelength tuning free features has been designed to integrate with\nthe semiconductor optical amplifier (SOA) and passive arrayed waveguide grating (AWG). By implementing hybrid multicasting\nand multiplexing, the system has been able to support a PON system with full flexibility function for managing highly efficient\ndynamic bandwidth allocation to support the 4????Ã?â??10 Gb/s TWDM-PON system used to connect 4 different PON links using fixed\nwavelength OLT transceivers with maximum 38 dB link loss.
