Experimental demonstration of super-symbol transmission for improved fiber nonlinearity tolerance.

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.
