Abstract:
A wavelength division multiplexing optical transmission system transmitting wavelength division multiplexed signal light including a plurality of wavelength bands, comprising:an optical transmission path comprising a first transmission section provided, by connecting: a first optical fiber having positive wavelength dispersions and positive dispersion slopes relative to said plurality of wavelength bands, respectively; and a second optical fiber having negative wavelength dispersions and negative dispersion slopes relative to said plurality of wavelength bands, respectively; said first transmission section having wavelength dispersion characteristics set such that compensation ratios by said second optical fiber for wavelength dispersions and dispersion slopes caused within said first optical fiber become maximum for a reference wavelength band which is one of said plurality of wavelength bands; and dispersion compensation means capable of compensating wavelength dispersions caused within said first transmission section of said optical transmission path, for said plurality of wavelength bands except for said reference wavelength band.
