Abstract
The present invention relates to an optical transmission line enabling WDM communications in a wide signal light wavelength band centered at a wavelength of 1.55 &mgr;m, in which nonlinear optical phenomena are less likely to occur; and an optical fiber constituting a part of the optical transmission line. The optical fiber has a dispersion D (unit: ps/nm/km) and a dispersion slope S (unit: ps/nm,/km) satisfying the conditions of −83≦D≦−18 and 0.0050×D≦S≦0.0025×D; and, as characteristics with respect to light having a wavelength of 1.55 &mgr;m, an effective area of 15 &mgr;m,or more and a bending loss of 50 dB/m or less when wound at a diameter of 20 mm.
