Experimental performance comparison of duobinary formats for 40 Gb/s long-haul transmission
Résumé
We experimentally compare the performance of various types of duobinary modulation formats for 40 Gb/s long-haul transmission. After having measured their respective robustness to accumulation of ASE noise, chromatic dispersion, PMD and intra-channel nonlinear effects, we show that transmission in excess of 2000 km can be envisaged.
