Abstract

An optical waveguide fiber including a core region, an inner clad layer surrounding and in contact with the core region and an outer clad layer surrounding and in contact with the inner clad layer. The refractive index percent of the radii of the core region, the inner clad layer and the outer clad layer are chosen from the following ranges: the index of the core region within the range of from about 1.332 to about 1.628; the index of the inner clad layer within the range of about 1.30 to about 1.591; the index of the outer clad layer within the range of from about 1.305 to about 1.595; the outer radius of the core region within the range of from about 1.71 &mgr;m to about 2.09 &mgr;m; and, the outer radius of the inner clad layer within the range of from about 4.41 &mgr;m to about 5.39 &mgr;m.
