How Fusion Splicer can be used for Fibre Optic Splicing

How Fusion Splicer can be used for Fibre Optic Splicing

Posted On September 11, 2020

Now that fibre deployment has become common, and splicing has moved from the OSP into the data centre environment and enterprise. When it comes to fusion splicing, it uses localised heat to melt and fuse together the ends of the two optical fibres. This preparation process includes taking out protective coating from the fibre, inspection of fibre-end faces and cleaving.

While fusion splicing is available for many decades, it is a trusted method for permanent fusing. When it comes to two optical fibres, they require to be of a particular length and to repair a broken fibre link. In order to do fusion splicing, you would require Fusion Splicer, which is a fibre optic splicing machine.

How does Fusion Splicer work?

Fusion splicers work when joining two optical fibres from one end to the other end with the use of heat. Both the fibres should be fused so that the light passing through the fibres is not disrupted but reflects from the splice. Thus, the splice and the area around it that are strong because of virgin fibre. The fusion splicer apparatus has two fixtures in which the fibres are mounted with two electrodes. With the help of an inspection microscope, it will review the placement of the prepared fibre ends that go into the fusion-splicing setup. These fibres are then put into the apparatus, straightened and then fused.

First, fusion splicing will use nichrome wire which is the heating unit required to fuse or melt the fibres together. With the new fusion splicing techniques, it has switched the nichrome wire with a fractional Co2 laser, electric arcs or gas flames that heat the fibre ends, and this makes them fuse together. The small fusion splice, in addition to the creation of automated fusion-splicing machines, will make an electric arc fusion.

Mechanical Splicing vs Fusion Splicing

As you know, two kinds of optic fibre splicing are available. Fusion splicing is one, and the other is mechanical splicing. When it comes to mechanical splicing, there are two fibre optic cables kept together from one end to other inside a sleeve with the help of a mechanical apparatus. Here, these fibres are not joined permanently but held together so that the light can easily pass from one end to the other end. While in fusion splicing two fibres are fused or fixed together with the help of an electric arc. In today’s environment, the fusion splicing is very popular. This is because it acts as a reliable join that has lower insertions loss, and there is next to no back reflection. This is why Fusion splicing is applied to single-mode fibres and in some cases to multimode fibres.

In conclusion, it is safe to say that fusion splicing allows permanent low-loss connections that are done fast and have its advantages over several other competing technologies in the market. Additionally, the fusion splicers can be designed to provide enhanced features and high-quality performance which makes very affordable as well.
