Low bend loss optical fiber

An optical fiber comprising:

• 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 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 Δ1MAX>Δ4>Δ2>Δ3, wherein the difference between Δ4 and Δ2 is greater than or equal to 0.01 and a profile volume, V3, equal to:
