Description

[0002] In actual optical fiber manufacturing work, optical fiber fusion splicing is often involved. By heating two sections of optical fiber and then joining them, it is usually necessary to remove the outer coating of the optical fiber. The most common method is to remove it with jaws, because the coating layer itself is a kind of glue. If the coating layer is not stripped off during fusion splicing, it will burn into ash, and the burning process of the coating glue will also destroy the thermal field distribution at the melting point, reducing the quality of fusion splicing. Currently, cleaning work mostly uses manual handheld sanitary napkins for wiping. This method is time-consuming and labor-intensive and can easily break and damage the optical fiber.
