Abstract:
A dispersion compensating optical fiber used by connection to a single-mode optical fiber that has zero dispersion in the vicinity of a wavelength of 1.3 &mgr;m or by connection to a compensated optical fiber whose dispersion characteristic in a 1.5 &mgr;m-wavelength band is substantially the same as that of the single-mode optical fiber, said dispersion compensating optical fiber characterized in that a dispersion value in a predetermined wavelength band in the 1.5 &mgr;m-wavelength band of a connected optical fiber is set at âˆ’1 ps/nm/km through 1 ps/nm/km, and a dispersion value in one or more predetermined wavelength bands different from the predetermined wavelength band in the 1.5 &mgr;m-wavelength band is set at âˆ’5 ps/nm/km through 5 ps/nm/km.
