摘要： 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.

摘要： 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.
