Abstract
According to embodiments, an optical fiber may include a core portion comprising a radius r, a centerline C, a numerical aperture NA greater than or equal to 0.15 and less than or equal to 0.25, a graded relative refractive index profile having a maximum relative refractive index Δand an α value greater than or equal to 1 and less than or equal to 3. The core portion may include an up-dopant with a graded concentration from the radius rto the centerline Cand an attenuation dopant with a constant concentration from the centerline Cof the core portion to the radius rof the core portion. The optical fiber is multi-moded for wavelengths of light within a range from 800 nm to 1350 nm and an attenuation of the optical fiber wavelengths between 800 nm and 1000 nm is greater than or equal to 0.5 dB/m.
