ABSTRACT:
There is disclosed a dispersion-compensating optical fiber exhibiting, at a wavelength of 1500 nm, a chromatic dispersion of −30 ps
m/km or less, a ratio (S/D) of −0.08
m to +0.05
m between chromatic dispersion D and dispersion slope S, a polarization mode dispersion of 0.3 ps/km1/2or 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 μm.
