摘要： A single mode optical waveguide fiber having a relatively large effective area and low dispersion includes a segmented core having at least two segments (30, 32, 34) each defining a radius, a refractive index profile and a relative refractive index percent. The waveguide fiber also includes a clad layer (36) surrounding and in contact with the core and having a relative refractive index. The refractive index profiles are selected to provide total dispersion at a wavelength of about 1550 nm of within the range of about 11 ps/nm-km to about 14 ps/nm-km, and total dispersion slope at a wavelength of about 1550 nm of within the range of about 0.045 ps/nm2-km to about 0.055 ps/nm2-km. The refractive index profiles are further selected to provide an effective area greater than or equal to 60 µm2, and attenuation at a wavelength of about 1550 nm of less than or equal to 0.22 dB/km.

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： A negative total dispersion waveguide fiber having low attenuation and compresses the launched signal pulse when the laser is positively chirped. The laser is provided at optimum bias, which results in positive chirp, but no dispersion penalty is incurred in the link. The waveguide fiber is used a dispersion compensating fiber in a high performance multiplexed telecommunications link. Curve (96) in figure 8 representative of a link comprising fiber having negative dispersion waveguide fibers. Curve (98) is representative of a link comprising fiber having negative dispersion at 1550 nm in accordance with the invention. Curve (100) is representative of a link comprising fiber in accordance with the invention and a laser source that is even more positively chirped thanthe laser to generate curve (98).
