Abstract
A boron-free glass composition for use in fiber optics is disclosed. In the field of fiber optics, light is transmitted from one point to another by small diameter fibers. These fibers are composed of a central core surrounded by an outer cladding or sheath. The glass compositions of this invention can be used as the core glass or the sheath glass.
