ABSTRACT:
An electric furnace for fusing optical fibers has a body made of insulating material. A fiber channel is provided wherein the fibers to be fused are positioned. To facilitate the insertion of the fibers a slot is provided which extends from the fiber channel to the surface of the body. Coil channels are provided around the fiber channel each having an opening to the fiber channel in the fusion area. During the fusion process the fibers are under tension to stretch the coupling region and the light coupling is monitored until the desired level is achieved.
