Abstract
An optical fiber that includes a silica core and a cladding surrounding the core is disclosed, the optical fiber having a low attenuation. In embodiments, the optical fiber has an attenuation at 1550 nm of about 0.1420 dB/km. Furthermore, the diameter of the core may be larger than a fundamental mode field diameter of the optical fiber at a wavelength of 1550 nm. In embodiments, the core is doped with an alkali dopant.
