Among the many domestic brands, TFN's optical fiber fusion splicer is recommended. TFN fusion splicer covers a wide range of models, and there are corresponding fusion splicers for various high, medium and low demands. So, how to choose a specific model when choosing a TFN brand optical fiber fusion splicer?
Select by fiber type>>
For modern fiber optic networks, each fiber optic manufacturer manufactures and sells a unified standard of SMF/MM fiber, but also various other types of fiber, including less sensitive BIF (bend insensitive fiber) and NZDSF, depending on construction needs (non-zero dispersion-shifted fiber, designed to overcome the problems of dispersion-shifted fiber). In order to splice these fibers with high precision and low loss, a more powerful fiber identification function is required. Among the single-core optical fiber fusion splicers, the entry-level TFN fusion splicer S3 to the high-end fusion splicer S7 constitute a product lineup that is very suitable for these tasks. These models all have high-performance optical fiber identification capabilities.
Select by network type>>
The TFN splicer lineup also features dedicated FTTH splicers S3 and M3 . For situations such as the last mile connection of FTTH networks, a certain degree of loss is acceptable to some extent, and TFN fusion splicers S3 and M3 are popular in access networks. There are many other products available to suit the functionality and cost required for each network build.
Choose according to the construction environment>>
With the increase of connection transmission capacity between metropolitan area networks or data centers, the number of fiber optic cables has increased, and the number of cores that need to be spliced for each job has increased from hundreds to tens of thousands. In order to perform these works efficiently, conveniently and quickly, the most important thing is to be able to perform fusion splicing and protective sleeves quickly and multiple times in a short period of time.
In such environments, the most suitable fusion splicer, such as the lightweight and easy-to-handle four-motor core alignment fusion splicer S5
Other things to consider when selecting a product based on the work environment are features that provide durability in outdoor construction work, such as resistance to dust, rain, shock and vibration, and long-lasting performance at high altitudes.
Core Alignment Fusion Splicer>>
Core aligned splicing is currently the most commonly used fusion splicing technique. Core alignment fusion splicers use a combination of image and light detection systems that "see" the fiber core to measure and monitor core position during the alignment process.
This provides precise fiber alignment resulting in a typical splice loss of only 0.01dB. Compared to cladding alignment, core alignment fusion splicers are more expensive, more powerful, more flexible, and less sensitive to cable and environmental changes. Core alignment fusion splicers have long been the method of choice for high-speed trunk lines, backbone networks, specialty fiber applications and optical component manufacturing due to their high precision and reliability. TFN's core alignment fusion splicer lineup covers FT-3 FT-7 S7 FM-89.
Cladding Alignment Fusion Splicer >>
More basic fusion machines employ cladding alignment. The fibers sit in a holder or V-groove and are "physically" aligned according to the outer diameter of the fiber cladding. The core is tuned inwards and outwards.
The advantages of this method are the low cost of the technology required and the high speed of alignment and fusion, so it is still used in low-cost field fusion machines and ribbon fusion machines. However, because the outer diameters are aligned, it does not mean that the cores will be perfectly aligned. Cladding alignment splicers typically have higher losses and lack the features and flexibility of higher end splicers.
