Title: Optical fiber transmission line for wavelength division multiplexingtransmission system

Abstract: An optical transmission system for transmitting an optical signal throughan optical fiber transmission line includes a first optical fibertransmitting the optical signal and having a first zero-dispersionwavelength shorter than a wavelength of the optical signal, and a secondoptical fiber transmitting the optical signal from the first optical fiberand having a second zero-dispersion wavelength longer than the wavelengthof the optical signal. A first nonlinear effective cross-sectional area ofthe first optical fiber is larger than a second nonlinear effectivecross-sectional area of the second optical fiber.
