Abstract:
A nonlinear dispersion-shifted optical fiber, comprising:an optical medium configured to have characteristics that include, a dispersion slope at a wavelength of 1550 nm falls within a range of 0.001 to 0.1 ps/nm2/km, a margin of fluctuation of the chromatic dispersion in a longitudinal direction of the optical fiber at a wavelength of 1550 nm falls within a range of 0.01 to 3 ps/nm/km, and a nonlinear constant n2/Aeff at a wavelength of 1550 nm is not smaller than 15Ã—10âˆ’10/W, wherein n2 is a nonlinear refractive index and Aeff is a effective core area.
