We discuss the modeling of linear and nonlinear signal propagation in the multi-mode fiber channel. Specifically, we introduce a generalized Stokes-space representation to describe signal evolution in such fibers and discuss the effect of modal dispersion representing the delay spread. We show that this phenomenon is described by a single real-valued vector whose modulus is Nakagami distributed. Furthermore, we describe nonlinear propagation in multi-mode fibers, and show that in realistic scenarios it can be modeled by means of coupled generalized Manakov equations.

Abstract
We discuss the modeling of linear and nonlinear signal propagation in the multi-mode fiber channel. Specifically, we introduce a generalized Stokes-space representation to describe signal evolution in such fibers and discuss the effect of modal dispersion representing the delay spread. We show that this phenomenon is described by a single real-valued vector whose modulus is Nakagami distributed. Furthermore, we describe nonlinear propagation in multi-mode fibers, and show that in realistic scenarios it can be modeled by means of coupled generalized Manakov equations.File in questo prodotto:
