摘要： A dispersion flattened non-zero dispersion shifted optical waveguide fiber which includes a central core region surrounded by an outer cladding region, the central core region having an alpha less than 4. The optical fiber has a dispersion at a wavelength of about 1550 nm of between about 4 ps/nm/km and about 8 ps/nm/km, and a dispersion slope of less than 0.025 ps/nm2/km at every wavelength between about 1525 nm and 1650 nm.

摘要： A Dispersion Compensation (DC) fiber and transmission line including the same. The DC fiber has a refractive index profile having a central core with a core delta (Δ1) value greater than 1.5%, a moat surrounding the central core having a moat delta (Δ2) value less negative than -0.65%, and a ring surrounding the moat having a positive ring delta (Δ3). The DC fiber's refractive index profile is selected to provide total dispersion less than -87 and greater than -167 ps/nm/km; dispersion slope more negative than -0.30 ps/nm2/km; and kappa of greater than 151 and less than 244 nm, all at 1550 nm. The DC fiber, when used in transmission lines, may provide low average residual dispersions across the C, L, C+L and S bands when such lines include transmission fibers with total dispersion between 4 and 10 ps/nm/km, and a positive dispersion slopes of less than 0.045 ps/nm2/km at 1550 nm. Further embodiments are described that include Raman pumping.
