Abstract :
By using the advantages of symmetry, a novel architecture of orthogonal frequency division multiplexing passive optical network (OFDM-PON) is proposed. It can not only achieve flexible protections but also provide the function of adding users conveniently. By utilizing the characteristics of ring based optical access network, the network keeps strong survivability against the fibers´ failures. Based on a novel remote node (RN) with symmetrical structure and an expansible optical network unit (ONU), the network can add new ONUs easily. Simulation and analysis show that it can achieve perfect performance. Furthermore, the system also has low BER (bit error rate) and SER (signal error rate) for the different kind of signals, besides the system can adapt a variety of working modes.
