There is disclosed a dispersion-compensating optical fiber exhibiting, at a wavelength of 1500 nm, a chromatic dispersion of -30 ps/nm/km or less, a ratio (S/D) of -0.08/nm to +0.05/nm between chromatic dispersion D and dispersion slope S, a polarization mode dispersion of 0.3 ps/kml/<1/2 >or less, and a transmission loss of 1 dB/km or less, and an excess loss of 0.2 dB/km or less due to OH group in a wavelength band of 1.4 mum.
