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 3000 ppm. 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.
Claims13
An optical fiber package comprising an optical fiber having a light transmitting core, the light transmitting core having a core diameter and a coating layer surrounding the light transmitting core, wherein an amount of chlorine in the light transmitting core is homogeneous and at least 3000 ppm by weight and whereby the light transmitting core exhibits a reduction in hydrogen induced attenuation losses when compared with light transmitting cores not comprising chlorine that is homogeneous and at least 3000 ppm by weight, the reduction in the hydrogen induced attenuation losses observed over operating and transmitting wavelengths in the range from 1000 nm to 1600 nm.
