    Abstract: Disclosed is a negative total dispersion waveguide fiber having low attenuation and sufficiently good resistance to bend loss that attenuation is not impacted by cabling or otherwise buffering the waveguide. The total dispersion slope of the waveguide fiber is positive so that the zero dispersion wavelength is greater than 1600 nm. The waveguide fiber may advantageously be used in a link having a distributed feedback laser as a signal source. The negative dispersion of the waveguide in accordance with the invention compresses the launched signal pulse when the laser is positively chirped. The laser is operated at optimum bias, which results in positive chirp, but no dispersion penalty is incurred in the link. The waveguide fiber in accordance with the invention may also be advantageously used as a dispersion compensating fiber in a high performance multiplexed telecommunications link.

    Abstract: 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/nm -km to about 0.055 ps/nm -km. The refractive index profiles are further selected to provide an effective area greater than or equal to 60 µm , and attenuation at a wavelength of about 1550 nm of less than or equal to 0.22 dB/km.

    Abstract: Multi-core optical fibers are provided in various embodiments of the present invention which include a plurality of cores. At least two cores (602, 604) of the plurality of cores have different associated mean propagation constants at a reference wavelength. The difference between the associated mean propagation constants may be selected to reduce cross-talk between the at least two cores as compared to cores having a same associated mean propagation constant. A primary coating (614, 618) of light absorbing material may be positioned between the cores to further reduce cross-talk. Also provided are methods for manufacturing the same and wavelength division multiplexing systems using the same.

    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.
