Abstract: To improve the potential security threats of WDM-PON access network, a novel WDM-PON based on quantum key distribution FPGA controller of passive decoy state modified model is presented here. QKD FPGA is responsible for 1.25 Gbps upstream PRBS source, clock regeneration, phase modulation control, key sifting, privacy amplification, and upstream time-divided-multiple-access control on quantum channels. An 8-user network experiment shows that over 20 km fibre, the mean secure exchange key rate can reach up to 500 bps in total, with the acceptable quantum bit error rate below safe limit and a few impact on classical channels. This scheme can provide a promising way for the coexistence between quantum key distribution and classical data service.
