ABSTRACT:
An optical fiber includes a glass fiber having a glass core and a cladding that contains voids that are spaced apart from the core, in contact with the core, or form a substantial portion of the core. The voids act as trapping sites for ingressing molecules from the surrounding environment, thereby reducing the effect of such molecules on the fiber's light-transmission properties.
