An optical waveguide fiber including a core region having a refractive index and an outer radius. The optical waveguide fiber also includes an inner clad layer surrounding and in contact with the core region, the inner layer having a refractive index and an outer radius. The optical waveguide fiber further including an outer clad layer surrounding and in contact with the inner clad layer, the outer clad layer having a refractive index. The refractive index 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 from 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 mu m to about 2.09 mu m; and, the outer radius of the inner clad layer within the range of from about 4.41 mu m to about 5.39 mu m. In another embodiment, the refractive index and 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 1.338 to about 1.636; the index of the inner clad layer within the range of from about 1.307 to about 1.597; the index of the outer clad layer within the range of from about 1.311 to about 1.603; the outer radius of the core region within the range of from about 2.61 mu m to about 3.19 mu m; and, the outer radius of the inner clad layer within the range of from about 5.31 mu m to about 6.49 mu m. <IMAGE> |
