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-mum and 1.55-mum 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 mum to 1.60 mum, the zero-dispersion wavelength existing within a wavelength range of 1.37 mum to 1.50 mum, and has a positive dispersion slope at the zero-dispersion wavelength, thereby enabling favorable optical communications utilizing each signal light in the 1.3-mum and 1.55-mum wavelength bands sandwiching the zero-dispersion wavelength.
