Optical coupler packaging structure

The invention relates to the technical field of optical couplers, in particular to an optical coupler packaging structure. Through the arrangement of the ceramic substrate assembly and the conductive metal, on one hand, the tension resistance of the conductive metal can be improved, the possibility of wire breakage is greatly reduced, and on the other hand, the voltage resistance of the product is improved to a certain extent through the relatively high insulation and voltage resistance of the ceramic substrate assembly; the ceramic substrate assembly is used for supporting and protecting the conductive metal, the voltage resistance performance can be further improved by enlarging an electric gap, the conductive metal cannot shake in the welding process, and therefore the welding yield is guaranteed under the condition that the voltage resistance performance is met, and in addition, the optical fiber and the light reflecting coating are arranged, so that the welding quality is improved.
