Real-time FPGA transmitter and receiver for coherent optical OFDM

Abstract

We demonstrate a real-time FPGA implementation of coherent optical OFDM transmitter and receiver. It is implemented using two 2.5 GS/s DACs and one FPGA for transmitter, two ADCs and one FPGA for receiver, and FPGA based real-time digital signal processing for coherent optical OFDM transmission.
