ABSTRACT:
An optical waveguide fiber is provided that includes a core and a cladding, where the core includes an alpha profile, wherein alpha (α) is greater than 2.5 and less than 3.0. The core and the cladding provide a fiber with an attenuation of less than 0.331 dB/km at a wavelength of 1310 nm, an attenuation of less than 0.328 dB/km at a wavelength of 1383 nm, an attenuation of less than 0.270 dB/km at a wavelength of 1410 nm, and an attenuation of less than 0.190 dB/km at a wavelength of 1550 nm. Methods for producing the optical fiber are also provided.
