Abstract

Dual-frequency laser sources are very promising for nonlinear fiber optics [1,2]. Recently [2] we have suggested an ultra long distance nonlinear fiber optic data transmission using dual-frequency laser sources. Such a transmission has all the advantages of the soliton transmission: dispersive compensation of nonlinear effects; stability against perturbations of the fiber parameters (dispersion, mode area, etc.) along the fiber length; stability of data streams in a chain of lumped amplifiers; potential for multi-channel wavelength division multiplexing (WDM). Here we show that a WDM data transmission system employing dual-frequency laser sources is more stable against interchannel interference in comparison with a conventional soliton system.
