Abstract :
A novel scheme to generate coherent 112 optical sub-carriers with subcarrier spacing of 25 GHz is proposed and experimentally demonstrated. By using these coherent optical subcarriers, we have successfully generated 10-Tbit/s (112×100 Gbit/s) single channel optical OFDM polarization multiplexing QPSK signal with the bandwidth of 2.8 THz and the optical signal noise ratio greater than 20 dB (0.1nm bandwidth for each subchannel). We have transmitted the 11.2-Tbit/s optical OFDM signal over 640-km SMF-28 with an amplifier span of 80 km and EDFA-only.
