| Summary: | To achieve flexible packet routing in a time wavelength-division multiplexing passive optical network (PON) architecture, most proposed systems use a tunable transceiver in the optical line terminal (OLT). The tunable transceiver is attractive for use in a PON system because it is able to broadcast and multicast packets within the entire PON system, being limited only to a single PON link. The proposed all-optical packet routing (AOPR) module was designed to incorporate a fixed-type wavelength OLT transmitter with a continuous-wave pump probe signal module. The design of the module is based on the ALL-ON method to support all broadcast signals, which replaces the wavelength tuning feature in the tunable OLT transmitter. The proposed architecture was designed using the multicasting cross-gain modulation (XGM) method. In this proposed design, the XGM function of the OLT system becomes a part of the AOPR OLT transmitter. The arrangement of this design aims to generate single or multiple wavelengths in a downstream direction in each OLT PON port. The measurement results revealed that the proposed system can handle a total of 160-Gb/s broadcast downstream bandwidth to serve 16 PON links using 16? with a maximum of 2048 users |
