Abstract
Disclosed is an optical fiber having a desired dispersion value to sufficiently suppress a non-linearity phenomenon, that is, a four-wave mixing phenomenon, occurring at a channel spacing of 50 GHz while minimizing the expense consumed for a compensation for dispersion. The optical fiber satisfies optical characteristics defined by a dispersion value of 7 to 10 ps/nm-km at a wavelength of 1,550 nm, a zero dispersion wavelength of 1,450 nm or less, and a cut-off wavelength of 1,250 nm or less. The optical fiber includes a core having a desired diameter (d ) and a desired refractive index (n ), the cladding surrounding the core and having a refractive index (n ) less than the (n ), of the core (n <n ) or (n ) less than the outer cladding (n <n ). The (n ) of the inner cladding may also be less than the (n ) of the core and more than the (n ) of the outer cladding.
