摘要

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％ FEC threshold.Within each channel,we achieve the spectral efficiency of 6.85 bit/s/Hz in C/L band.
