| http://www.w3.org/ns/prov#value | - Fibers such as shown in FIG. 1 may be constructed by placing a rod-like member of the high-index glass within a tubular member of the low-index glass, heating and causing said tubular member to collapse and fuse with the rod-like member, heating the assembly thus formed to a suitable fiber-drawing viscosity and thereafter drawing the assembly down to a desired fiber size.
