Metal-Coated Fiber

Metal coated optical fibers can be mainly divided into aluminum coatings (with a temperature resistance of about 400 ° C), copper alloy coatings (with a temperature resistance of about 600 ° C), and gold coatings (with a temperature resistance of about 700 ° C) according to the coating materials, and can be divided into two categories according to the preparation process: online metal coating during fiber drawing and post-treatment plating (such as magnetron sputtering, electroplating, chemical plating).
