<p>An optical fiber (10) having section (A) of first kind where the chromatic dispersion in a predetermined wavelength band is greater than a predetermined positive value x and the chromatic dispersion slope is negative and section (B) of second kind where the chromatic dispersion in the same wavelength band is smaller than -x and the chromatic dispersion slope is positive, or an optical fiber where the chromatic dispersion in a predetermined wavelength band is greater than the predetermined positive value x and the chromatic dispersion slope is negative.</p> |
