Abstract
We demonstrate the error-free transmission of directly modulated 2.5-Gb/s, 10-Gb/s, and 40-Gb/s CWDM/DWDM signals over negative dispersion fiber (dispersion: -2.5 ps/km/nm @1550 nm) without dispersion compensation. The results indicate that the metro core/access network could be implemented cost-effectively by using the negative dispersion fiber and directly modulated lasers.
