For the purpose of studying the key technologies for future ultra-high-rate large-capacity optical transmission systems
we realize a 16-superchannel WDM transmission of 1.92 Tbit/s/ch Polarization Division Multiplexed(PDM) 16QAM Orthogonal Frequency Division Multiplexing(OFDM)over 80 km SMMF
the total data rate of which is 30.7 Tbit/s in C band occupancy.Each superchannel consists of 45 subchannels with a spectral width of 250 GHz and a spectral efficiency of 7.68 Gbit/s/Hz.The BER of all channels after 80 km transmission is smaller than 2×10-2
