Abstract
A method to improve the robustness of an elongated electrode used in an arc fusion apparatus for splicing optical fibers by reshaping the tip of the elongated electrode by electrolytic etching. The method involves reshaping the substantially sharp tip of the elongated electrode by immersing it as the anode in an electrolyte solution, the electrolyte solution is one capable of dissolving an oxidation product of the elongated electrode. Then a second electrode is provided at a predetermined distance from the elongated electrode in the electrolyte solution. Afterward, an electrical current is passed, or caused to flow, between the elongated electrode and the second electrode for a predetermined period of time through the electrolyte solution to reshape the substantially sharp tip of said elongated electrode into a predetermined profile having a substantially round tip.
