Abstract
An optical fiber includes a central glass core region comprising maximum refractive index delta percent Δ, a first inner annular region surrounding said core comprising refractive index delta percent Δ, a depressed annular region surrounding said inner annular region and comprising Δand a third annular region surrounding the depressed annular region comprising refractive index delta percent Δ; wherein the third annular region comprises chlorine an amount greater than 0.2 weight percent in a region which is within 5 microns from the depressed annular region, wherein Δ>Δ>Δ>Δ. The difference between Δand Δis greater than 0.01 and profile volume, |V| is at least 50% Δμm.
