Abstract: A polarisation maintaining optical fiber package is described. The fiber comprises a core having a core diameter, a first protective coating layer surrounding the core, the first protective coating layer having a first protective coating inner diameter, a first protective coating outer diameter and a first protective coating thickness between the first protective coating inner diameter and the first protective coating outer diameter, a second protective coating layer surrounding the first protective coating layer, the second protective coating layer having a second protective coating inner diameter and a second protective coating outer diameter, the first protective coating layer comprising a material having a first hardness and the second protective coating layer comprising a material having a second hardness, wherein the thickness of the first protective coating layer is in the range from 6% to 33% of the core diameter. The thickness of the coatings in the package is such that the optical fiber core exhibits a reduction in strain and stress sensitivity over a wide range of temperatures, even down to around minus 20 degrees C.

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.
