How to Choose Fiber Optic Fusion Splicer

Though the specific functions and characteristics of various types of fiber optic fusion splicer on the market are slightly different, the elements of purchase remain the same. For example, the market demand for single-core optical fiber fusion splicers is high. it is not difficult to choose the most suitable fusion splicer for your measurement requirements. Below is a figure showing the factors to consider when purchasing a fusion splicer.

Factors to consider when purchasing a single-core fiber optic fusion splicer:


When purchasing a fusion splicer, you must first consider price range of the product. The pricing of the splicer depends on factors such as splicing loss, display effect, battery life, etc.

Splice loss

For fusion splicers, splicing loss is the most important indicator, which directly determines the quality and efficiency of the project.

Battery life

Fusion splicers are mostly used in the field, and battery life is very important. Generally speaking, a skilled operator can splice up to 150 fibers a day. Therefore, the requirement for the battery is that it can work continuously for at least 6 hours or can be connected and heated more than 150 times.


The operators of the fusion splicer are mostly ordinary workers, and ease of use is also an important factor.

Heating time

The time for one optical fiber connection is about 9s, and the time to heat shrink a 60mm standard heat shrinkable tube is generally more than 35s. The heat shrinkage problem has become the biggest factor restricting the further improvement of the overall construction efficiency. In addition, the shortening of heating time also means that the efficiency of the heater is improved, and the energy consumption of the battery is reduced.

Welding time

Although the welding time has little effect on the overall construction efficiency, the ability to complete high-quality splicing in a relatively short time also represents the overall technical level of the welding machine to a certain extent.

Display effect

The imaging effect of the optical fiber allows the operator to have a more intuitive understanding of the entire splicing process. In addition, the judgment of the fiber end face, the core adjustment, and the evaluation of the splicing effect by the instrument are all based on the image.

Volume and weight

For tools that are mainly used in the field, miniaturization has always been the trend of development and improvement of fiber optic fusion splicer. Smaller volume and weight will bring more convenience to users in construction.

Interface function

At present, the main interfaces of the fusion splicer are USB and VGA interfaces. Among them, the main function of the USB interface is to perform system upgrades and data output; while the VGA interface is used for video output, and an external display device with VGA interface can be used to observe the real time display of the splicer. This function is mostly used for training and teaching.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
