ABSTRACT:
The present invention aims to provide a dispersion-shifted fiber which can effectively restrain nonlinear optical effects from occurring and has a configuration suitable for long-haul light transmission. The dispersion-shifted fiber has, as various characteristics at a wavelength of 1,550 nm, a dispersion level of 1.0 to 4.5 ps
m/km in terms of absolute value, a dispersion slope not greater than 0.13 ps
m.sup.2 /km in terms of absolute value, an effective core cross-sectional area not less than 70 .mu.m.sup.2, and a transmission loss not greater than 0.25 dB/km with respect to light in a 1.55-.mu.m wavelength band.
