Abstract :
Pseudo-linear transmission over 2000 km at 40-Gb/s is demonstrated with 100-km amplifier spacing and without using FEC. A simple optimized dispersion map based on conventional terrestrial link design is used to increase the non-linearity threshold enabling higher signal powers to be launched. A Q-value of 15.9 dB is measured after transmission over 2000-km transmission line using 2-dBm launched signal power.
