    Abstract: Disclosed is a single mode optical waveguide having a segmented core of at least two segments. The relative refractive index, the index profile and the radial dimensions of the core segments are selected to provide an optical waveguide fiber having properties suitable for a high performance telecommunication system operating in the wavelength window of about 1530 nm to 1570 nm. Embodiments of the invention having two, three and four segments are described to eliminate non-linear effects, such as FWM and SPM, which occur in a high performance, high rate systems, the effective area of the waveguide is made to be greater than about 60 mu m , more preferably greater than 65 mu m , and most preferably greater than 70 mu m . The total dispersion is preferably positive and equal to at least 2 ps/nm-km at 1530 nm. This total dispersion together with a total dispersion slope less than about 0.1 ps/nm -km insures a minimum FWM effect over the wavelength window.

    Abstract: An optical fiber is disclosed herein comprising a core having an alpha parameter in the range of approximately 2 to approximately 8, a maximum index percent difference between the core and a cladding in the range of approximately 0.3% to approximately 0.5% and a core diameter in the range of approximately 6.0 to approximately 16.0 microm and a cladding. The optical fiber has a bandwidth of at least approximately 0.6 GHz.km at 850 nm, and is configured for multimode operation at a wavelength less than 1300 nm and single mode operation at a wavelength of at least approximately 1300 nm. The fiber also has significantly reduced intermodal noise. Also disclosed herein is a method of designing such a fiber, a fiber optic system provided such a fiber and a method of operating a fiber optic system with such a fiber.
