Abstract:
An optical fiber package is described comprising a light transmitting core having a core diameter, a coating layer surrounding the core, and wherein the amount of chlorine in the light transmitting core region is homogeneous and comprises at least 3000ppm. The fiber package is such that the optical fiber core exhibits a reduction in the hydrogen induced attenuation losses. A method for fabricating the optical fiber package is also disclosed, which comprises carrying out chemical vapour deposition reactions in a substrate tube and collapsing the tube in a C12 atmosphere to form a preform.
