Zusammenfassung:This letter proposes and experimentally demonstrates a secure orthogonal frequency-division-multiplexing passive optical network (OFDM-PON) based on the chaos scrambling in the OFDM frequency domain. The Logistic map is adopted for the chaos mapping. The chaos scrambling algorithm can dynamically allocate the scrambling matrices for different OFDM frames according to the initial condition, which enhance the confidentiality of the physical layer. It achieves a secure transmission at physical layer in OFDM-PON for data encryption. The experiment successfully transmits 8.37-Gb/s OFDM data with Logistic mapped chaos scrambling over 25-km single-mode fiber (SMF), and the results indicate the robustness against eavesdropping.
