ABSTRACT:
The invention provides a stimulated Brillouin scattering suppressed optical fiber which is easy to be produced, has an almost zero chromatic dispersion over the entirety of an optical fiber in the lengthwise direction, and has a low light loss. That is, in an optical fiber having a property, by which the chromatic dispersion with respect to optical communication signals becomes zero, obtained by changing the relative refractive index difference of the optical fiber and core diameter in the same increase or decrease direction, the relative refractive index difference of the core and the core diameter R are changed in the lengthwise direction of the optical fiber, and the core diameter R is made smaller in line a decrease the relative refractive index difference of the core while the core diameter R is made larger in line with an increase of the refractive index difference, whereby the chromatic dispersion the designated wavelength band is made nearly equal to zero in the entirety of the optical fiber in the lengthwise direction.
