DISPERSION CO M PEN SAT10 N US I NG FREQUENCY SHIFT MID-SPAN SPECTRAL INVERSION WITHOUT

We report the first system demonstration of dispersion compensation using mid-span spectral inversion without frequency shqt. By a two-pump FWM scheme, we achieve 120-kni penalty-free transmission at 2.5 Gbith over standard single-mode fiber using a directly modulated DFB source
