Nonlinear Frequency-Division Multiplexing in the Focusing Regime

TL;DR

This paper compares the achievable data transmission rates of nonlinear frequency-division multiplexing (NFDM) and wavelength-division multiplexing (WDM) in single-mode fiber, demonstrating NFDM's superior performance at the same power and bandwidth.

Contribution

It provides a quantitative comparison of NFDM and WDM rates under identical constraints, highlighting the advantages of NFDM in the focusing regime.

Findings

NFDM achieves higher rates than WDM at the same power.

Rate performance of NFDM improves with increased transmit power.

WDM's achievable rates are limited compared to NFDM in the studied regime.

Abstract

Achievable rates of the nonlinear frequency-division multiplexing (NFDM) and wavelength-division multiplexing (WDM) subject to the same power and bandwidth constraints are computed as a function of transmit power in the standard single-mode fiber. NFDM achieves higher rates than WDM.
