Abstract
In a wavelength division multiplexed transmission path, the used waveband can be selected from the widest possible waveband among the S-band, C-band, and L-band. The wavelength division multiplexed transmission path has a dispersion-compensating transmission path comprising a dispersion-shifted fiber, which has positive chromatic dispersion throughout a range of wavelengths from 1460 nm to 1630 nm, and one type of dispersion-compensating fiber, or two or more types of dispersion-compensating fiber having different chromatic dispersion having negative chromatic dispersion in a compensation waveband, selected from the abovementioned range; the residual chromatic dispersion of the wavelength division multiplexed transmission path is adjusted so as to be greater than −1.0 ps/nm/km or equal to and less than or equal to +1.0 ps/nm/km in a used waveband of the wavelength division multiplexed transmission path, which is selected from the abovementioned range.
