The Tx DACs operated at a record-low 1.15 sample/symb thanks to advanced anti-alias filters. The SEDP was 11,327 (bkm)/(s-Hz), highest for PM-64QAM.Nespola, A.Straullu, S.Bosco, G.Carena, A.39th European Conference on Optical Communication: 39th European Conference on Optical ...
摘要: Dark-pulse microresonator combs exhibit efficient pump-to-comb power conversion. Using on-chip pump powers of 21 dBm, we show 20-channel PM-64QAM-based data transmission. These results represent the highest-order modulation format encoded onto any integrated comb....
64QAM指一个符号表示6个数字bit,相当于对数据做了1分为6的处理,速率降低了1/6。单载波只用一个频率点;多载波用几个频点来传送信息,如果n个频率给一个用户传送信息,则速率可以提高n倍。400G双载波通过DSP进行信号处理,将1个400G分为2路200G PM-16QAM信号,1路200G占用37.5 GHz频谱,这样400G只需要75 GHz频谱...
对于PM-16QAM情况,子载波间隔为50 GHz,对于PM-32QAM和PM-64QAM情况,子载波间隔均为37.5 GHz,总共允许24 $ times $ 1.0、32 $ times $ 1.0和32 $ times $ 1.2Tb / s C频段上的超通道,导致潜在的C频段容量分别为24.0、32.0和38.4 Tb / s。现场传输后,与前向纠错(FEC)阈值所需的$ rm {OSNR_ {0.1...
