Abstract
An optical fiber that can sufficiently suppress the generation of four-wave mixing and that can widen the bandwidth of wavelength of signal light. The optical fiber of the present invention has (a) a chromatic dispersion whose absolute value is not less than 8 ps·nm−1·km−1 and not more than 15 ps·nm−1·km−1 at a wavelength of 1.55 &mgr;m and (b) a dispersion slope whose absolute value is not more than 0.05 ps·nm−2·km−1 at a wavelength of 1.55 &mgr;m. It is more desirable that the optical fiber have (a) a chromatic dispersion whose absolute value is not less than 8 ps·nm−1·km−1 and not more than 12 ps·nm−1·km−1 at a wavelength of 1.55 &mgr;m, (b) a dispersion slope whose absolute value is not more than 0.03 ps·nm−2·km−1 at a wavelength of 1.55 &mgr;m, (c) a chromatic dispersion whose absolute value is not less than 5 ps·nm−1·km−1 at wavelengths between 1.45 and 1.65 &mgr;m, (d) an effective area not less than 45 &mgr;m2 at a wavelength of 1.55 &mgr;m, and (e) a two-meter cutoff wavelength not less than 1.…
