Water-peak-suppressed non-zero dispersion shifted fiber for full spectrum coarse WDM transmission in metro networks

We have successfully developed the water-peak-suppressed NZ-DSF best suited for full spectrum CWDM transmission in the metro networks. Its chromatic dispersion is well under control so as to match directly modulated DFB-LDs and future high-bit-rate transmission in the entire wavelength band. Transmission experiments including the 1.4 /spl mu/m signal wavelength have verified its transmission performance in a wide spectral range from 1.3 /spl mu/m to 1.6 /spl mu/m.
