Abstract
An optical fiber termination device wherein temperature rise is minimized when light power is high or a power laser is used therewith. A first optical fiber is connected to a second optical fiber by fusing the core of the first optical fiber to the clad of the second optical fiber with a discharge generated between electrodes. The first optical fiber is inserted into a hole at the center of a ferrule and then the first optical fiber is fastened to the ferrule by fusing them. Thereafter, the edge surface of the ferrule is finished by polishing it. The second optical fiber is covered with a protective cover. Light coming from the core of the first optical fiber is incident on and scattered into the clad of the optical fiber. The light reflected toward the light source is greatly decreased by this structure.
