Abstract
The present invention relates to an optical transmission line comprising a structure for effectively lowering both of nonlinearity and dispersion slope, and an optical transmission system including the same. The optical transmission line comprises, as a repeating transmission line disposed between stations, a single-mode optical fiber having a zero-dispersion wavelength in a 1.3-&mgr;m wavelength band and a dispersion-compensating optical fiber for compensating for the chromatic dispersion of the single-mode optical fiber. The optical transmission line has an average dispersion slope S of −0.0113 ps/nm /km or more but 0.0256 ps/nm /km or less at a wavelength of 1550 nm, and an equivalent effective area EA of 50 &mgr;m or more at the wavelength of 1550 nm, whereas the average dispersion slope S and the equivalent effective area EA are designed so as to satisfy a predetermined condition such that the bending loss falls within a permissible range of 2 dB/m or more but 10 dB/m or less.
