Real-time optical OFDM transmissions based on FPGA with 6.93bit/s/Hz spectral efficiency by using simple directly modulated DFB laser and DAC/ADC with sampling rate as low as 2GS/s without inline amplifier are experimentally demonstrated. 7.09-Gb/s OFDM signals with subcarrier modulation format up to 512-QAM can be successfully transmitted over 50-km SSMF with adopted HD-FEC (3.8×10−3). The robustness...
