Abstract
The present invention relates to an optical fiber which enables favorable optical communications in 1.3-.mu.m and 1.55-.mu.m wavelength bands, and an optical transmission system including the same. The optical fiber according to the present invention has only one zero-dispersion wavelength within a wavelength range of 1.20 .mu.m to 1.60 .mu.m, the zero-dispersion wavelength existing within a wavelength range of 1.37 .mu.m to 1.50 .mu.m, and has a positive dispersion slope at the zero-dispersion wavelength, thereby enabling favorable optical communications utilizing each signal light in the 1.3- .mu.m and 1.55- .mu.m wavelength bands sandwiching the zero-dispersion wavelength.
