Abstract

An optical fiber includes a central glass core region comprising maximum refractive index delta percent Δ1, a first inner annular region surrounding said core comprising refractive index delta percent Δ2, a depressed annular region surrounding said inner annular region and comprising Δ3 and a third annular region surrounding the depressed annular region comprising refractive index delta percent Δ4; wherein Δ1MAX>Δ4>Δ2>Δ3. The difference between Δ4 and Δ2 is greater than 0.01 and profile volume, |V3| is at least 60% Δμm2.
