Abstract :
The first experimental demonstration of real-time 3Gb/s Optical OFDM(OOFDM) modems is reported, using off-the-shelf components and improved IFFT/FFT design. In directly modulated DFB laser-based, optical-amplifier- and dispersion-compensation-free, IMDD systems, 16QAM-encoded OOFDM transmission over 500m MMFs (75km MetroCor SMFs) is achieved with optical power penalties of 1.7dB (−1.9dB) at 1.0×10−4 BERs.
