Abstract
An optical fiber having an axial direction and a cross section perpendicular to said axial direction, said optical fiber comprising: a first light guiding fiber portion (604) having a cladding region with a plurality of spaced apart cladding voids extending longitudinally in the fiber axial direction and a core region bounded by said cladding region, and a solid light transparent fiber portion (602) having a first end facing the first light guiding fiber portion and a second end forming an end face of the optical fiber, said solid light transparent fiber portion providing a hermetic sealing (601) of the cladding voids of the first light guiding fiber portion; a method of its production, and its use, such as an optical fiber connector and an article comprising a microstructured optical fiber with hermetically sealed end face.
