What is fiber optic fusion splicing and how is it used?

Fiber optic fusion splicing is a technique to join two fiber optic cables using controlled heat. This process is typically performed with a fusion splicer device, which aligns the fiber cores and creates a permanent bond by heating them.

Fusion splicing reduces light loss and back-reflection along the fiber. Fiber optic cables are multi-layered and delicate, requiring careful preparation to ensure a high-quality connection.

After fusion, protecting the splice and preventing excessive bending at the joint helps ensure reliability and long-term performance.

What is a fusion splicer?

A fusion splicer is a device that holds two fiber ends in alignment and uses precise settings to generate a weld between the fiber cores. The device improves alignment and connection quality, enabling reliable splices.

What are the steps of fiber optic fusion splicing?

1. Stripping - the polymer protective coating is removed to expose the fiber core for preparation.
2. Cleaning - the exposed fiber is cleaned to remove contaminants that could affect the splice.
3. Cleaving - the fiber end is cut to a precise end-face geometry for a clean, flat surface.
4. Fusion splicing - the fibers are placed in the splicer, settings are applied, and the weld is formed. A protective sleeve is usually applied after the weld.

Conclusion

Having the right ancillary equipment and following proper handling and maintenance practices helps ensure that fiber optic networks operate reliably.
