  • Dispersion slope compensating optical waveguide fiber
    Patent number: 6829422
    Abstract: Disclosed is a dispersion compensating and dispersion slope compensating single mode optical waveguide fiber. The refractive index profiles of waveguide fibers in accord with the invention are disclosed and described. These index profiles provide a waveguide fiber having negative total dispersion and negative total dispersion slope so that a standard waveguide fiber is compensated over an extended wavelength range. A telecommunications link using the fiber in accord with the invention is also disclosed and described. A standard fiber to compensating fiber length ratio in the range of 1:1 to 3:1 is shown to give optimum link performance with respect to limiting non-linear dispersion effects.

  • HIGH CAPACITY OPTICAL WAVEGUIDE FIBER
    Publication number: 20040202435
    Abstract: Disclosed is an optical waveguide fiber that simultaneously exhibits large effective area and good resistance to bend induced attenuation, as measured by any of the tests known in the art. The cut off wavelength is controlled to allow single mode operation over a wavelength range that extends from about 1340 nm to 1650 nm. The optical waveguide fiber refractive index profile is simple in design allowing cost effective manufacture.

  • Method of connecting optical fibers, an optical fiber therefor, and an optical fiber span therefrom
    Patent number: 6789960
    Abstract: A bridge fiber and a method of connecting two other dissimilar optical waveguide fibers is presented. The bridge fiber may be utilized to connect positive dispersion fibers or step index single mode fibers to compensative fibers, such as dispersion compensation fibers or dispersion-slope compensation fibers.
