Fusion splicing is the process of using heat to melt two fibre optic ends together. The fibre optic ends are first prepared for splicing by removing the protective coating from each end. A process called cleaving is then completed which scores and breaks the ends. The process requires precise treatment by experienced fibre optic engineers who use a microscope to inspect the ends.
Fusion splicing apparatus is used to mount the two fibres with a microscope to help in the placement. Once the fibres are aligned in the splicer they can be fused using carbon dioxide lasers, electric arcs or gas flames.
The most popular method to fuse the ends is using the electric arc technique due to the increased use of new tools.
