Increased Amplifier Spacing in a Soliton System with Partial Dispersion Compensation

Abstract

Recently very impressive results of soliton transmission at bit rate as high as 20 Gb/s over 9000 km were demonstrated in a system where the dispersion was periodically compensated [1,2]. The use of a dispersion compensating element in a soliton transmission system was in fact a milestone which demonstrates that the application of techniques thought to be compatible only with linear (NRZ) systems can improve the performance of nonlinear systems as well.
