A multiple fiber optical cable includes bundled plural optical fibers. In each of the optical fibers to be bundled in the optical cable, a positive dispersion section having a positive chromatic dispersion in an optical signal wavelength and a negative dispersion section having a negative chromatic wavelength and a negative dispersion section having a negative chromatic dispersion section in the optical signal wavelength are alternately arranged so that the chromatic dispersion characteristic of the optical fiber alternately changes in the longitudinal direction. The chromatic dispersion characteristics of the respective bundled plural optical fibers coincide with each other at at least the position of each end of the multiple fiber optical cable. The member which surrounds the optical fibers of the optical cable is provided with the identification marks for identifying the chromatic dispersion characteristics at the individual locations in the longitudinal direction.
