ABSTRACT:
A reverse dispersion optical fiber having a small waveform distortion caused by non-linearity wherein an effective core area is made at least 50 μm2and a dispersion at a wavelength of the 1.55 μm band is made not more than −10 ps
m/km and a dispersion management optical transmission line having a small waveform distortion obtained by connecting a positive dispersion optical fiber and that reverse dispersion optical fiber in that order along a direction of signal transmission and having a total dispersion of substantially zero.
