Abstract: A clad optical fiber having an air space between its core and cladding. The air space allows outgasing of the fiber core and cladding material during fabrication of the fiber and forms an internally reflective interface with the core for transmitting light through the fiber by total internal reflection.

Abstract: A method of making a length of drawn multifiber conduit of improved optical quality including the steps of heating a section of juxtapositioned optical fibers to a temperature suitable for rapid drawing to reduced cross-sectional size, the volume of materials of said section being sufficient to yield the entire drawn conduit, keeping interstices between the juxtapositioned fibers open adjacent opposite ends of the section for outgasing during the heating step and drawing the heated section rapidly to the cross-sectional size and length desired of the conduit so as to quickly expose the resulting conduit to a chilling atmosphere for immediate quenching and avoidance of internal gas bubble formation.
