在960 km标准单模光纤上实现了112 Gb/s奈奎斯特16-QAM半周期单边带（SSB）副载波调制（SCM）信号在C波段的单通道直接检测传输。研究了长距离传输条件下单边带-单载波调制系统中的光纤克尔非线性效应。通过在发射端应用预失真数字反向传播（DBP）方法来抑制非线性失真。与仅进行色散补偿的预失真相比，使用DBP可实现1.02 dB<inline-formula><tex-math notation="LaTeX">${Q} ^{2}$</tex-math></inline-formula>因子改善。
We demonstrate the single channel direct detection transmission of 112 Gb/s Nyquist 16-QAM half-cycle single sideband (SSB) subcarrier modulation (SCM) signal over 960 km standard single mode fiber with erbium-doped fiber amplifier-only amplification at C-band. Fiber Kerr nonlinearity in SSB-SCM systems is investigated for long distance transmission. The nonlinear distortion is suppressed by the pre-distorted digital back-propagation (DBP) method applied at the transmitter side. With DBP, a 1.02 dB <inline-formula> <tex-math notation="LaTeX">${Q} ^{2}$ </tex-math></inline-formula> factor improvement is achieved compared with chromatic dispersion compensation only pre-distortion.
