Abstract
A method of forming low loss splices between single-mode optical fiber ends involves taking prepared fiber ends and aligning the one with the other by inserting them into opposite ends of the bore of a ferrule, and fusing the fiber ends together by applying thermal energy thereto by means of an aperture in the wall of the ferrule. Splices prepared in this way have losses of less than 0.5 dB. The use of a precisely dimensioned ceramic ferrule enables the use of splicing apparatus which does not incorporate means for 3-dimensional micromanipulation.
