Abstract
A hermetically sealed optical fiber assembly according to the present invention includes an optical fiber having a metallic coating on at least one intermediate part thereof which is exposed by removing part of a coating on the optical fiber, a hermetic connecting component made of metal which receives the metallic coated part therein, and a brazing part for tightly fixing the metallic coated part of the optical fiber to an inner wall of the metal hermetic connecting component.
Claims5
A hermetically sealed optical fiber assembly comprising:
- an optical fiber having a metallic coating on at least one intermediate part thereof which is exposed by removing part of a coating on the optical fiber;
- a hermetic connecting component made of metal which receives the metallic coated part therein;
- and
- a brazing part for tightly fixing the metallic coated part of the optical fiber to an inner wall of the metal hermetic connecting component.
A manufacturing method for a hermetically sealed optical fiber assembly, said method comprising the steps of:
- forming a metallic coated part on at least one optical fiber;
- inserting an exposed part of the optical fiber which has been subjected to the metallic coating into a metal hermetic connecting component;
- and
- forming a brazed part between the metallic coated part and an inner wall of the hermetic connecting component;
- wherein, said step of forming the metallic coated part further comprises the steps of:
- removing the coated part of the optical fiber to expose the core thereof;
- dipping the exposed optical fiber in a sensitizer solution and adsorbing Sn2+ in a surface thereof that is made hydrophilic;
- dipping the optical fiber in an activator solution after washing with water to deposit Pd nuclei by a redox reaction;
- dipping the optical fiber in an electroless plating solution to form an electroconductive film;
- and
- performing electroplating using an electrolyte.
