摘要

本文报道了基于发射机的数字信号预失真的DP-16QAM (28 Gbd)信号的非线性容差测量，显示了光纤发射功率相对于预失真(6个未补偿的SMF跨度约1.5 dB)的系统性能增益，以及非线性阈值跨度比例因子的明显降低。

Spectral pre-distortion with FPGA and DAC at 448-Gb/s DP-16QAM improving nonlinear threshold power

Non-linear tolerance measurements of DP-16QAM (28 Gbd) signals with transmitter based digital signal pre-distortion are reported, showing systematic performance gains of fibre launch power versus pre-distortion (~1.5 dB for 6 uncompensated SMF spans) and a distinct reduction of the non-linear threshold spans scaling factor.
