Abstract

The solution of the present invention is a stimulated brillouin scattering (SBS) suppressing optical fiber which adds additives such as Ge, P, F singly or in combination to a core consisting of quartz glass, forms a stepwise core refractive index distribution, and increases SBS threshold power by setting the difference in concentration of an additive between adjacent steps of this stepwise refractive index distribution to at least a specified concentration difference, or by setting the difference in refractive index between adjacent steps to at least a specified refractive index difference. Since the constitution of the SBS suppressing optical fiber can increase SBS threshold power, SBS can be suppressed and zero-dispersion wavelength and mode field diameter are set to function as parameters equivalent to those of a normal single mode fiber (SMF), whereby no disadvantage such as an increase in connection loss will not occur even if applied to a transmission line.
