The difference between Fiber Cleaver and Machine

1. Fiber Cleaver
The optical fiber cold joint cutting knife is a cutting method that does not rely on heat source. It uses a high-speed rotating super-hard alloy cutting blade to cut the optical fiber into the required length. This cutting method is suitable for cutting single-mode and multi-mode optical fibers. It can cut optical fibers with reinforcement materials, and the cutting speed is very fast, usually reaching a speed of tens of meters per minute.
Advantages:
1. High cutting quality, flat and smooth incision, no damage to the fiber core.
2. No heating treatment is required, no thermal stress is generated on the fiber, and the phenomenon of different refractive index areas in the optical fiber is avoided, which reduces the transmission efficiency.
3. No need to use special fixed equipment, fast cutting speed, high production efficiency.
4. Low maintenance cost and long service life.
Disadvantages:
1. High requirements on the material and precision of the cutting knife.
2. High equipment cost.
2. Hot melt cutting knife
The hot melt cutting knife is a method of cutting optical fiber using a high-temperature heat source. It uses a heat source to heat the optical fiber to near the melting point, and then quickly stretches the heated optical fiber to break it, thereby achieving the purpose of cutting. This cutting method is suitable for single-mode optical fiber, and the cutting speed is usually slow.
Advantages:
1. It has a wide range of uses and can be applied to the cutting of most single-mode optical fibers.
2. It is not easy to generate dust.
3. The cutting speed is slow and can achieve precise length requirements.
Disadvantages:
1. The cutting quality depends on the heating temperature and the stretching speed. If the heating temperature is not enough or the stretching speed is not fast enough, it is easy to cause the incision to be rough, affecting the optical fiber transmission effect.
2. Special fixed equipment must be used, which occupies a large area of ​​the site.
3. The equipment cost is high and the maintenance cost is also high.
In summary, both the optical fiber cold joint cutting knife and the hot melt cutting knife have their own advantages and disadvantages. You should choose the cutting method that suits you according to the specific usage scenario and needs.
