　　By using PDM-OFDM-16QAM modulation,all-Raman amplification,coherent detection,and 7%forward error correction(FEC)threshold,we successfully demonstrate 63-Tb/s(368×183.3-Gb/s)signal over 160-km standard single mode fiber(SSMF)transmission in the C-and L-bands with 25-GHz channel spacing.368 optical channels with bandwidth spacing of 25 GHz are generated from 16 external cavity laser sources.After 160-km SSMF transmission,all tested bit error rate(BER)are under 3.8×10-3,which can be recovered by 7...
