A method of real-time dispersion equalization for optical OFDM system based on FPGA is researched in this paper. According to the principle of dispersion equalization, a simulation platform for the OFDM-PON system is setup. The results show that the dispersion equalization module based on FPGA can effectively compensate for the dispersion damage, and that the performance of OSNR can be improved by about 0.5~1 dB and the requirement for real-time processing system can be met.
