Optimal Dispersion ofNZ DSF in 40 Gbit/s DWDM Transmission

Numerical and experimental verification of optimal dispersion ofNZ-DSF in 40Gb/s-based DWDM transmission are performed using 240km simple transmission line. The results show that dispersion of +8ps/nni/km is effective in 40 Gb/s as well as 10 Gb/s.
