OPTICAL FIBER FUSION SPLICER TYPES (FUSION SPLICING MACHINES) EXPLAINED IN DETAIL
WHAT IS FUSION SPLICING?
Fiber splicing is the process of permanently joining two fibers together. Unlike fiber connectors, which are designed for easy reconfiguration on cross-connect or patch panels.

There are two types of fiber splicing – mechanical splicing and fusion splicing.

Mechanical splicing doesn’t physically fuse two optical fibers together, rather two fibers are held butt-to-butt inside a sleeve with some mechanical mechanism. You will get worse insertion loss and back reflection in mechanical splices than in fusion splices (the second type we are introducing below).Mechanical splicing is mostly used for emergency repairs and fiber testing. You can check out some mechanical  splice products here.

(but this video explain second method of splicing.)

 The second type splicing is called fusion splicing. In fusion splicing, two fibers are literally welded (fused) together by an electric arc. Fusion splicing is the most widely used method of splicing as it provides for the lowest insertion loss and virtually no back reflection. Fusion splicing provides the most reliable joint between two fibers. Fusion splicing is done by an automatic machine called fusion splicer (fusion splicing machines). We will focus on fusion splicers in this tutorial.

:: WHAT IS A FUSION SPLICER?
As we said above, fusion splicer is the machine used to weld (fuse) two optical fibers together. This process is called fusion splicing. The fiber ends are prepared, cleaved, and placed in alignment fixtures on the fusion splicer. At the press of a button, the fiber ends are heated with electrodes, brought together, and fused.

Fusion splicers are automatic machines that you need to either choose factory recommended settings or you set the splicing parameters yourself. There are five basic steps to fusion splicing with a splicing machine.

1. Put on the fusion splice protection sleeve.

2. Strip the fiber. Strip back all fiber coatings down to the 125um bare fiber. Clean the bare fiber with 99% isopropyl alcohol.

3. Cleave the fiber. The fiber needs to be cleaved with a high precision cleaver. Most splicing machines come with a recommended cleaver. Fiber cleaving is a very important step as the quality of the splice will depend on the quality of the cleave.

4. Put the fibers into the fiber holders in the fusion splicer. Press the start button to start the fusion splicing

5. Heat shrink the protection sleeve to protect the splicing joint.
