ABSTRACT:
An optical fiber splice and the method of forming it are described wherein a hollow cylindrical glass member is provided, the member having a bore along the longitudinal axis thereof. Fluid at a pressure in excess of ambient pressure is provided to the bore while the member is subjected to localized heating of the member to the softening point of the glass. In this manner, a bubble is formed within the member bore under the influence of said heating and pressure. For more uniform bubbles, the member may be rotated about its longitudinal axis while it is subjected to said fluid pressure and heating. The splice member is subsequently formed by severing the cylindrical member at the location of the bubbles. Optical fibers may be inserted into the ends of the splicing member and cemented in place.
