Unknown What is the true Shannon capacity of the optical fiber channel including Kerr nonlinearity, and can nonlinear Fourier transform (NFT) based transmission systems approach this capacity limit in practical deployments? u-fiber-nonlinearity-capacity-limit-shannon

Active Hypotheses

Hypothesis Nonlinear Fourier transform (NFT) based transmission using the soliton basis will achieve capacity closer to the nonlinear Shannon limit than conventional WDM-DSP systems in the high-power regime, because NFT decouples nonlinear channel interactions into independent soliton eigenvalue channels. medium
