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.

Abstract: An optical transmission system is provided. The system includes a series of consecutive blocks of optical fiber. Each block of the system includes a first, second and third series of spans of optical fiber, where the second series of spans compensates for accumulated dispersion in the first and third series in the wavelength range of transmission. Optionally either the first or third series can be omitted.

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.

Abstract: An apparatus for transporting an optical signal is provided. The apparatus includes sections of optical fiber span with at least one section negative dispersion, negative slope fiber positioned at a distance from the output.

Abstract: Disclosed is a telecommunications system link that includes plurality of spans each having a transmission fiber and a compensating fiber. The compensating fiber is selected to completely compensate dispersion slope while only partially compensating total dispersion. This configuration compensates dispersion over an operating wavelength range while at the same time providing a transmission path having non-zero dispersion.

Abstract: Disclosed are refractive index profiles for total dispersion compensating optical waveguide fibers for use in high data rate, long length telecommunications systems. The optical waveguide fibers in accord with the invention provide substantially equal compensation of total dispersion over a range of wavelengths, thus facilitating wavelength division multiplexed systems. Also disclosed are spans of optical waveguide fiber that include a length of transmission fiber together with a length of the compensating fiber. The spans are joined end to end in series arrangement to form the optical waveguide fiber part of a telecommunication system.
