Optical fiber and optical transmission system including the same |
摘要 |
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. <IMAGE> |
