    Abstract: PROBLEM TO BE SOLVED: To allow the parameter modeling in the waveguide fiber to have a core refractive index distribution generating a set of beforehand selected operation characteristics and optimizing attenuation for its special refractive index distribution by that a minimum distribution attenuation waveguide fiber is provided with a minimum effective refractive index and a minimum change rate of the square of a propagation constant when the waveguide is bent. SOLUTION: This core refractive index distribution is a regular type one, and the refractive index distribution of a solid line is provided with a central point 24 of a comparatively low relative refractive index percent Δ%. For instance, a distribution part 6 of a higher relative refractive index percent Δ% may be an (α) distribution or a rounded step distribution also. Further, definitions of a radius and a width are shown. For instance, the radius 3 of a central distribution is a line that a core central line prolongs to a point that the distribution 6 performed with an extrapolation method means an (x) axis. Then, the parameter modeling in the waveguide fiber is provided with the minimum effective refractive index and the minimum change rate of the square of the propagation constant of the minimum distribution attenuation waveguide fiber when the waveguide is bent.

    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.
