Abstract

PURPOSE:To decrease the positional fluctuation of an optical fiber with a temp. change and to improve the reliability of a device by using entirely a metallic material for fixing an optical fiber strand and optical fiber supporting capillary as well as the capillary and pipe. CONSTITUTION:Metallized layers 32, 33, 34, 35 are provided to the optical fiber supporting capillary 3 and the layer 35 is tapered. An optical fiber core 5 and the optical fiber strand 4 are inserted into the pipe 2 for fixing the capillary 3 and the core 5 and thereafter solder is thoroughly packed into the pipe 2. While the strand 4 is then passed into the central hole 31 of the capillary 3, the capillary 3 is inserted into the pipe 2. The capillary 3 is inserted from the tapered layer 35 side. The entire part of the pipe 2 is heated while the capillary 3 is pushed to melt the solder packed therein by which the strand 4 and the capillary 3 as well as the capillary 3 and the pipe 2 are simultaneously fixed.The reliability of the device is thus improved by using the metal having the shrinkage on the temp. change extremely smaller as compared with a resin adhesive agent in the stage of fixing.
