我们通过实验证明，与PM-8QAM相比，采用一种新的TCM格式，即8状态12QAM TCM，在3b/s/Hz下将150Gb/s信号的传输距离提高了27%。我们还证明了使用非线性补偿的多状态TCM传输距离的改善，范围从14%到26%，而PM信号的类似改善低于11%。
We demonstrated experimentally the improvement of the transmission distance by 27% of 150Gb/s signal at 3b/s/Hz with a novel TCM format, 8-state 12QAM TCM, compared to PM-8QAM. We also demonstrated improvement of the transmission distance for multiple state TCM using nonlinear compensation, ranging from 14% to 26%, while similar improvement was below 11% for PM signals.
