Abstract

The present invention concerns a negative-dispersion optical fiber for compensating in a shorter length for chromatic dispersion of a positive-dispersion optical fiber in a signal wavelength band, and an optical transmission line incorporating it. The negative-dispersion optical fiber has the following properties at the wavelength of 1550 nm; chromatic dispersion D of not more than -150 ps/nm/km; a dispersion slope satisfying such a condition that a ration thereof (S/D) to the chromatic dispersion D is not less than 2.0 X 10-3/nm nor more than 4.7 X 10-3/nm; and an effective area of not less than 12 µm2. For satisfying these properties, the negative-dispersion optical fiber (200) has, in the order stated from the center toward the outer periphery, a core region (210) of a maximum refractive index n1, a first cladding (221) of a refractive index n2 (< n1), a second cladding (222) of a refractive index n3 (> n2), and a third cladding (223) of a refractive index n4 (< n3).
