Non-zero dispersion shifted fiber with low cut off wavelength and large effective area

An optical fiber comprising:

• a core region defined by a region around a central longitudinal axis, wherein the core region further comprises at least one or more regions of:
• a first annular region defined from the central longitudinal axis to a first radius from the central longitudinal axis of the optical fiber, wherein the first annular region has a super Gaussian profile for a refractive index profile and has a first refractive index ranging between a maximum refractive index Δ1max and a second refractive index Δ2 in accordance with the super gaussian profile,
• a second annular region defined from the first radius to a second radius from the central longitudinal axis of the optical fiber and has a refractive index equivalent to the second refractive index Δ2, and
• a third annular region defined from the second radius to a third radius from the central longitudinal axis of the optical fiber and has a third refractive index Δ3,
• wherein the first annular region, the second annular region and the third annular region are concentrically arranged, and wherein the second refractive index Δ2 is less than the third refractive index Δ3 and the third refractive index Δ3 is less than the maximum refractive index Δ1max;
• and
• a cladding region defined from the third radius to a fourth radius from the central longitudinal axis of the optical fiber,
• wherein the optical fiber has at least one of a dispersion value in a range of −16.78 Ps/nm/km to −11.36 Ps/nm/km at a wavelength of 1310 nm and the dispersion value in a range of −4.02 Ps/nm/km to 0.15 Ps/nm/km at a wavelength of 1460 nm.
