Abstract
An optical fiber for long-distance optical communication networks has a zero dispersion wavelength value in the range of 1560 to 1570 nm and a dispersion gradient value, at a wavelength band of 1550 nm, in the range of 0.055 to 0.075 ps/nm2/km.
Claims8
An optical fiber for long-distance optical communication networks comprising:
- a core having a first region having a maximum refractive index at the center of the first region and a second region having a minimum refractive index and surrounding the periphery of the first region, and a clad having a predetermined refractive index higher than the minimum refractive index of the second region and surrounding the periphery of the core, said fiber having a zero dispersion wavelength value in the range of 1560 to 1570 nm and a dispersion gradient value, at a wavelength band of 1550 nm, in the range of 0.055 to 0.075 ps/nm2/km.
