What is the principle of optical fiber fusion splicing technology?

Fiber transmission has the advantages of wide transmission frequency band, large communication capacity, low loss, no electromagnetic interference, and cheaper than copper cable, and is becoming a new main transmission medium. Therefore, it is important to master and make good use of optical cable fusion and testing technology. Practice has proved that as long as we carefully understand the technical essentials of fusion and testing, practice more and pay attention to accumulating some skills, it is not difficult to master this technology to improve optical cable fusion quality and testing level. Huizhou optical cable fusion splicing manufacturers introduce the current mainstream optical fiber fusion splicing technology principles " Huizhou optical cable fusion welding The principle of the current mainstream optical fiber fusion splicing technology is simply:

What is the principle of optical fiber fusion splicing technology? 1. First, optical fiber alignment-mainly the lateral imaging and axis method, which performs image processing on the lateral imaging of the optical fiber, finds the characteristic value related to the position or azimuth of the optical fiber as the independent variable, and deduces the dependent variable (that is, the position of the optical fiber or azimuth information), and controls the translation and rotation of the optical fiber through a precision motor system to achieve alignment before fusion splicing;

2. After the alignment is completed, fusion is completed. Or is it the mainstream-pre-heating fusion method? First, clean discharge is used to remove dust on the end face of the optical fiber, then pre-discharge is used to preheat and shape the end face of the optical fiber. Finally, under the main discharge environment, one fiber is moved axially to complete the fusion of the two optical fibers and form an optical fiber fusion point. (PS. There are many methods for optical fiber alignment. For example, the active axial alignment method is different from what I said, but it is neither a literature review nor the other methods will be mentioned. Don't think that this is the only one.) You can recall the above words after reading the following. Huizhou optical cable fusion welding

Huizhou optical cable fusion splicing manufacturers remind: When putting the cut optical fiber into the fusion splicing machine, the requirement is that the cutting end face is kept 2-4mm away from the discharge needle. During the entire process from taking it out from the cutting knife to putting it into the fusion splicing machine in place, the cutting end face is not allowed. Touch other items, otherwise the end face will be contaminated, which will affect the quality of fusion splicing. This must be paid great attention to during operation.
