Abstract: 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/nm 2 /km at every wavelength between about 1525 nm and 1650 nm.

Abstract: An optical signal transmission link includes a first single mode optical fiber for receiving an optical signal, and a graded index multimode optical fiber for receiving the optical signal from the first single mode optical fiber. The multimode fiber of the transmission link is adapted to support the propagation of greater than or equal to 4 LP modes within the wavelength range of from about 1310 nm to about 1550 nm, has a mode field diameter of the fundamental mode of within the range of from about 3.0 mum to about 14.0 mum within the wavelength range of from about 1300 nm to about 1650 nm, and has a numerical aperture (NA) value of greater than or equal to about 0.16.

Abstract: 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 (DELTA1) value greater than 1.5%, a moat surrounding the central core having a moat delta (DELTA2) value less negative than -0.65%, and a ring surrounding the moat having a positive ring delta (DELTA3). 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.
