我们研究了波分复用（WDM）传输系统中的符号率的非线性惩罚的依赖关系，同时保持一个固定的频谱效率为几个偏振分复用（PDM）调制格式。传输性能被发现被改善高达1.6 dB的较低的符号率在3.5-56 GBd的范围内的WDM传输的情况下。
We investigate the dependence of nonlinear penalties on symbol-rate in wavelength-division-multiplex (WDM)-transmission systems while maintaining a fixed spectral efficiency for several polarization-division-multiplexed (PDM) modulation formats. Transmission performance is found to be improved by up to 1.6 dB for lower symbol rates over the range 3.5-56 GBd for the case of WDM transmission.
