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.

Abstract: Disclosed is a dispersion compensating optical fiber that includes a core surrounded by a cladding layer of refractive index DELTA c. The core includes at least three radially adjacent regions, a central core region having DELTA 1, a moat region having a refractive index DELTA 2 and an annular ring region having a refractive index DELTA 3, such that DELTA 1 > DELTA 3 > DELTA c > DELTA 2. The fiber exhibits a dispersion slope which is less than -1.0 ps/nm /km over the wavelength range 1525 to 1565, a dispersion at 1550 which is less than -30 ps/nm/km, and a kappa value obtained by dividing the dispersion value by the dispersion slope which is greater than 35 and preferably between 40 and 100.
