Regular perturbation is applied to space-division multiplexing (SDM) on optical fibers and motivates a correlated rotation-and-additive noise (CRAN) model. For <tex>$S$</tex> spatial modes, or 2 <tex>$S$</tex> complex-alphabet channels, the model has 4 <tex>$S$</tex>(<tex>$S$</tex> + 1) hidden independent real Gauss-Markov processes, of which 2 <tex>$S$</tex> model phase noise, 2 <tex>$S$</tex>(2 <tex>$S$</tex> - 1) model spatial mode rotation, and 4 <tex>$S$</tex> model additive noise… Expand

Capacity Limits of Optical Fiber Networks
We describe a method to estimate the capacity limit of fiber-optic communication systems (or ¿fiber channels¿) based on information theory. This paper is divided into two parts. Part 1 reviewsExpand
Nonlinearity Mitigation in WDM Systems: Models, Strategies, and Achievable Rates
TLDR
An NLI mitigation strategy is devised, which exploits the synergic effect of phase and polarization noise (PPN) compensation and subcarrier multiplexing with symbol-rate optimization and lower-bound the channel capacity. Expand

Properties of nonlinear noise in long, dispersion-uncompensated fiber links
TLDR
The true NLIN power is derived and it is verified that the NLIN is not additive Gaussian, but rather it depends strongly on the data transmitted in the channel of interest. Expand

EGN model of non-linear fiber propagation.
TLDR
This paper analyzes in detail the GN-model errors and derives a complete set of formulas accounting for all single, cross, and multi-channel effects that constitute the enhanced GN- model (EGN-model), which is found to be very good when assessing detailed span-by-span NLI accumulation and excellent when estimating realistic system maximum reach.

Upper bound on the capacity of the nonlinear Schrödinger channel
It is shown that the capacity of the channel modeled by (a discretized version of) the stochastic nonlinear Schrödinger (NLS) equation is upper-bounded by log(l + SNR) with SNR =Expand
