ABSTRACT:
An article suitable as an integral handle for an optical waveguide preform is disclosed. The article comprises a hollow tubular member defining a substantially longitudinal aperture and having one end thereof tapered and of diminishing wall thickness for the length of said taper. Adjacent the tapered end is disposed an outwardly extending protrusion which is embedded in one end of an optical waveguide preform forming an integral unit therewith. Means are provided for a substantially gas-tight connection to the handle so that a gaseous medium may be flowed through the handle and the optical waveguide preform in its porous soot form. Means are also provided for attaching and securing the composite structure to a source of gaseous medium. Also disclosed is the combination of an optical waveguide preform rigidly affixed to a handle.
