“…It was found that temporal properties of the QAM transmit sequence that are guaranteed to occur for short CCDM outputs yet not for long blocks lead to NLI mitigation. This effect is related to previous theoretical work on shaping for the nonlinear fiber channel predicting larger gains than for a linear channel [8] and also to temporal PS over a few time slots [9,10].…”

“…Nonlinear shaping gain can therefore be achieved by reducing the variance of the transmitted signal energy, in addition to the usual (linear) shaping gain that requires the reduction of the average signal energy. As a consequence, the overall shaping gain may exceed the famous 1.53 dB limit, and unlike the situation in the linear case, its maximal value may be achieved at finite code-length N , as was demonstrated in [15].…”

We propose a practical shaping algorithm for mitigating the effect of nonlinear phase-noise in fiber-optic transmission. The proposed scheme is most beneficial in single-span fiber communications systems of the kind considered for inter-datacenter communications. In such systems the correlation time of the nonlinear phase-noise is too short to allow the mitigation of nonlinear phase-noise by means of adaptive phase-recovery or equalization, but long enough for a shaping approach to be effective. We rely on the implementation of the shell mapping method, optimized so as to provide the largest sum of linear and nonlinear shaping gains.Index Terms-Optical communications, shell mapping, optimal shaping, fiber nonlinearity, nonlinear interference noise (NLIN). 0733-8724 (c)

“…The theoretical gains of such systems were analyzed in [56], where the constellation was restricted to a multi-dimensional ball, for which the mass is concentrated on a multi-dimensional sphere when the number of constellation symbols is large. It was shown that the gains potentially exceed the ultimate shaping gain on an AWGN channel of 1.53 dB.…”
