The fusion splicer is used to fuse two optical fibers end-to-end by fusion splicing. It is an indispensable tool for optical fiber OSP and indoor cable network installation. There are many models of fusion splicer available, their functions, functions and costs vary. There are hundreds of options to choose from, and it can become very difficult to choose the right fusion splicer for the job. In this article, we will discuss how to find the best fusion splicer for your application from the following aspects.

Single fiber fusion splicer VS. Large-scale welding machine

Single-fiber fusion splicers: typically splice 250-micron fibers, but can also accommodate 900-micrometer sheathed fibers, flat cables, and fusion splices on connectors (also called splices on connectors) that are primarily used in FTTH applications. Strip a piece of fiber, clean it, split it, and insert it into the fiber holder. Repeat the same process for another fiber placed in the opposite fiber holder. Newer single splicer models can splice in less than ten seconds and estimate attenuation (light loss). Of course, this is just an estimate, and OTDR should be used to test the fiber more accurately.

 Large-scale welding machine：The bulk or ribbon splicer can splice 1 to 12 optical fibers at a time. The fiber support determines the number of fibers that you can splice at once. Large-capacity fusion splicers are not as popular as single-fiber fusion splicers, but they are very efficient if used for cables that need to connect multiple optical fibers. If the number of optical fibers required exceeds 96, the cost per connector can be saved up to 65%.

Core Alignment Fusion Splicer VS. Cladding Alignment Fusion Splicer

Core alignment splicing is currently the most commonly used fusion splicing technology. Core alignment splicers use a combination of image and light detection systems that “view” the fiber cores to measure and monitor core position during the alignment process. This provides for precise fiber alignment, resulting in a typical splice loss of only 0.02dB. Compared to cladding alignment, it is more expensive, more powerful and flexible, and less sensitive to variations in the cable and environment.

Cladding Alignment Fusion Splicer: More basic fusion splicers use cladding alignment to align optical fibers for fusion splicing. The optical fibers are located in a bracket or V-groove and are "physically" arranged according to the outer diameter of the fiber cladding. The fiber core is adjusted inward and outward. The advantage of this method is that the required technical cost is low, and the alignment and splicing speed is fast, so it is still used in low-cost field welding machines and ribbon welding machines.

When choosing a fusion splicer, it is important to choose a reliable company because there are many suppliers of fusion splicers on the market.
