How to Use Fusion Splicers in Optic Fiber Cables


A  fusion splicer is a tool that joins two optical fibers at their end faces using an electric arc to create a single long fiber. The resulting junction, also known as a fusion splice, permanently unites the two glass fibers end to end, allowing optical light signals to move with negligible loss from one fiber to the other.

How does a fusion splicer function?

Fusion Splicers in the USA need to be meticulously cleaned, freed of their outer jackets and polymer coatings, and then properly split to create smooth, perpendicular end faces before they can be successfully fused together. 

The remaining parts of the procedure, which entail three steps, are then handled by the fiber optic fusion splicer. These steps include;

  • Alignment: 

To ensure that the resulting splice is as smooth and attenuation-free as possible, the fusion splicers in the USA make minute modifications to the locations of the fibers until they are perfectly aligned. The optical power meter, video camera, or viewing scope’s magnification allows the fiber optic technician to see the alignment of the fibers while they are being aligned.

  • Impurity Burn-Off: 

When it comes to fusion splicers in the USA, you can never be too clean because even a small amount of dust or other contaminations can seriously impair a splice’s space to transfer optic details. 

Many fusion splicers in the USA include an additional precautionary cleaning step in the process even if fibers are manually cleaned before being introduced into the splicing device. 

  • Fusion: 

The ends of the fibers should be fused together to produce a permanent splice once they have been appropriately positioned and any remaining moisture and dust have been burnt out. The optical fiber end faces are melted by the splicer’s second, bigger spark without the fibers’ sheathing and molten glass core rubbing against one another (keeping the cladding and core separate is quite essential for a good splice – it decreases the optic loss). The final fusion splice is created by connecting the melted fiber tips. 

The next step is to conduct estimated splice-loss testing. The majority of fiber fusion splicers in the USA often exhibit an optical loss of 0.1 dB or less.

The optical fiber fusion splicers in the USA are accurate, authentic, and practical optical fiber construction tool intended specifically for optical fiber network attachment, operation, and preservation. 

When building, inspecting, and maintaining optical cables, it is frequently utilized in the field of optical communication. Optical fiber fusion splicers in the USA are used in optic transmission to finish the attachment and maintenance of optical cables.

Using a fiber fusion splicer:

The procedure for using typical single-core fiber fusion splicers in the USA is essentially the same. Preparation instruments include dust-free paper, alcohol, optical fiber heat shrinkable tube, stripping pliers, and optical fiber cleavers.

  • After stripping the fiber optic cable, secure it to the fiber tray.
  • Run the heat-shrinkable tube through the optical fibers that have been stripped.
  • Select the splicing method and turn on the splicer’s power.
  • Make the fiber end face ready. Peel off the coating using a special wire stripping tool, clean the naked fiber with high-concentration alcohol, cut the fiber with a precision fiber cleaver, and adjust the cutting length as necessary.
  • Set up the fiber optic and gently close the fiber pressure plate to press the optical fiber.
  • Attach the optical fiber.

What is the purpose of fusion splicers?

By joining several cable segments together, fusion splicers can produce lengthy cable lengths. The only way to test the splice loss is with an OTDR, despite the fact that the splicer will estimate it.

What is the price of a fusion splicer?

A fusion splice in a drop site will cost $30–$60 in labor in addition to the splicing cost at a rate of $60–120/hr.

Do fusion splicers need to be calibrated?

Out-of-calibration fusion splicers will create subpar splices. You will lose time and money due to inaccurate OTDR measurements and shoddy connector splice linking cables. So, fusion splicers do need to be calibrated.
