This paper proposes a two-dimension encryption orthogonal frequency division multiplexing passive optical network (OFDM-PON) based on dynamic chaos-iteration. The correlation monitoring method is adopted to achieve dynamic key distribution between OLT and ONUs. It is shown that key space can be larger than 1086, which would be against exhaustive attack effectively. We experimentally demonstrate a...
The introduction of OFDM into PON networks is to leverage the merits of OFDM to provide the flexibility and reduce the cost. In this paper, we present our latest works on OFDM-PON. Firstly, we propose and demonstrate a novel OFDM-PON upstream transmission architecture with traffic aggregation by orthogonal band multiplexing. The multiplexed 10-Gb/s OFDM signal is collectively received. We also conduct...
In this paper, a passive optical network (PON) based on optical code division multiple access (OCDMA) is presented, and analyzed in detail. The proposed system can be applied to an optical access network with full services on demand, such as internet protocol, video on demand, telepresence and high quality audio. An OCDMA-PON combines advantages of PON and OCDMA technology. Simulation result elicits...
