Abstract :
The dominant penalties are wavelength chirp, line broadening due to optical back reflection, and mode partition noise due to insufficient side-mode suppression. Experimental results on pulse compression at 1550 nm and on penalty reduction by dispersion compensation are presented. The dispersion compensation is achieved by adding a negative dispersive fiber link to a standard fiber link with positive dispersion at 1550 nm. In this way it was possible to transmit 5 Gb/s over a 111-km fiber link
