Latest Patents
Ari Virekunnas holds a patent for a "Method and a device for the manufacturing of an optical coupler." This invention involves a method for manufacturing optical couplers that includes several steps. The process begins with removing the jacket material over a short distance from two or more optical fibers. The jacketless portions of the optical fibers are then brought into contact with each other. Following this, the optical fibers are fused together within the contact area and drawn into tapers. A key feature of this method is that the optical fibers are fused by heating them using an arc that is substantially parallel to the fibers. The arc is generated in a chamber that confines it in the direction of the radius of the fibers. It is excited and extinguished at a low frequency, allowing the arc to strike at varying points around the fibers. Additionally, the invention includes an oven designed for fusing fibers, which features a fusion chamber extending through a ceramic body and is equipped with electric electrodes at both ends to produce the necessary arc.
