Abstract :
We demonstrated 3.2 Tb/s (40 ch × 80 Gb/s) signal transmission over 1,000 km of TrueWave-RS fiber with 100 km span (25 dB loss) by the use of newly developed tandem electroabsorption modulators, LiNbO3 modulators, hybrid Raman/EDFA, dynamic gain equaliser filters, and passive filtering to suppress the linear cross talk. An optimum dispersion map was incorporated to further relax the nonlinearity based impairment on the system.
