What is fusion splicing and how is fusion splicer work

Fusion splicing is the act of joining two optical fibers end-to-end using heat by fiber fusion splicer. The goal is to fuse the two fibers together in such a way that light passing through the fibers is not scattered or reflected back by the splice, and so that the splice and the region surrounding it are almost as strong as the virgin fiber itself. 

 

The process of fusion splicing normally involves using fiber fusion splicer to melt or fuse the ends of two optical fibers together. The splicing process begins by preparing each fiber end for fusion.

    Placing protection sleeve over optical fiber

---

 

The above is one side of optical fiber which used for splicing, please place protection sleeve over optical fiber before stripping, cleaning, and splicing of fiber, unless user has other protection methods.

 

    Stripping optical fiber

---

 

Strip outer coating 30 to 40 mm from its tip with a stripping tool.

 

    Cleaning

---

 

Clean the optical fiber with alcohol impregnated gauze or lint-free tissue thoroughly.

 

    Fiber Cleaving

---

 

Cleaving the fiber by cleaver, the length is about 8~16mm. 

 

    Splicing the fiber

---

 

Before splicing, discharge the machine to suit to current environment, and set the right mode. 

 

    Heating sleeve 

---

 

After splicing, heating sleeve.
