We experimentally verified the enhanced nonlinear tolerance of probabilistic shaping (PS) 64QAM super symbol (SUP) transmission over both dispersion uncompensated and compensated standard single mode fiber (SSMF) links. PS-64QAM with SUP is found to provide ∼0.51- and ∼1.6-dB gains in OSNR over PS-64QAM with traditional probabilistic amplitude shaping, after ∼1000-km uncompensated and 320-km compensated links, respectively.

超符号传输提高光纤非线性容忍度的实验演示

我们通过实验验证了色散未补偿和补偿标准单模光纤（SSMF）链路上概率整形（PS）64QAM超级符号（SUP）传输的增强的非线性容限。发现带有SUP的PS-64QAM在经过约1000 km的无补偿链路和320 km的补偿链路之后，与传统的概率振幅整形相比，在PS-64QAM上的OSNR增益分别为〜0.51和〜1.6 dB。
