Steps of Fusion Splicing Explained Here

Permanently joining two fibers together is the process of Fiber splicing with a fiber splicer. These are designed for easy reconfiguration on patch panels or cross-connect, unlike fiber connectors.

 Fusion splicing is one type of splicing. By an electric arc, two fibers are welded (fused) together in fusion splicing. The most widely used method of splicing is Fusion splicing as it provides for virtually no back reflection and the lowest insertion loss. Between two fibers, Fusion splicing provides the most reliable joint. By an automatic machine called fusion splicer, Fusion splicing is done.

Fusion splicer

As we said above, used to weld (fuse) two optical fibers together, the fusion splicer is the machine. This process is known as fusion splicing. On the fusion splicer, the fiber ends are placed in alignment fixtures after being prepared and cleaved. The fiber ends are heated with electrodes at the press of a button. They are then brought together and fused.

You need to either set the splicing parameters yourself or choose factory-recommended settings as Fusion splicers are automatic machines.  To fusion splicing, there are five basic steps with a splicing machine.

• The sleeve for fusion splice protection must be used.
• The fiber is then stripped with a fiber stripper. Down to the 125um bare fiber, Strip back all-fiber coatings. With 99% isopropyl alcohol, clean the bare fiber.
• The fiber is cleaved. With a high precision cleaver, the fiber needs to be cleaved. With a recommended cleaver, most splicing machines come. On the quality of cleave, the quality of the splice is based.
• In the fusion splicer, Put the fibers into the fiber holders. To start the fusion splicing, Press the start button.
• To protect the splicing joint, the protection sleeve is Heat shrinked

Some tips for splicing technicians and contractors

• Maintain a clean splice environment and clean equipment, being especially wary of dusty and windy conditions.
• For maintenance and setup of all splice equipment, follow the applicable equipment manufacturer’s guidelines. Maintenance requirements are needed by all fusion splicers which in the operating manual should be described. They need occasional replacement and electrode alignment apart from cleaning regularly. For servicing, the manufacturer’s requirements must be followed.
• With the total link power budget in mind, Splice loss specifications should be set and the average splice loss must determine it.
• As an initial no-go or go evaluation of the splice, the estimated splice loss reading of the fusion splicer must be used.
