What are the differences between optical fiber cold splicing and optical fiber fusion splicing technology

Optical fiber transmission, that is, data and signal transmission using optical fiber as the medium. Optical fiber can not only be used to transmit analog signals and digital signals, but also can meet the needs of video transmission. Optical fiber transmission generally uses optical cables. The data transmission rate of a single optical fiber can reach several Gbps, and the transmission distance can reach tens of kilometers without the use of repeaters.

When light is transmitted in an optical fiber, loss occurs. This loss is mainly composed of the transmission loss of the optical fiber itself and the splicing loss at the fiber joint. Once the optical cable is ordered, the transmission loss of the optical fiber itself is basically determined, and the splicing loss at the optical fiber joint is related to the optical fiber itself and on-site construction.

Optical fiber is a very convenient tool for signal transmission. One of the slender optical cores of the cable can replace more than a thousand physical communication lines to complete a large number of long-distance communication tasks.

The 8 major advantages of optical fiber transmission are as follows:

1. High sensitivity, free from electromagnetic noise interference.

2. Small size, light weight, long life and low price.

3. Insulation, high pressure resistance, high temperature resistance, corrosion resistance, suitable for work in special environments.

4. The geometric shape can be adjusted according to environmental requirements, and the signal transmission is easy.

5. High bandwidth, large communication volume, small attenuation, and long transmission distance.

6. The signal crosstalk is small and the transmission quality is high.

7. High confidentiality.

8. Easy to lay and transport materials.

Two technologies can be used for the termination of the optical cable: fusion and cold splicing.

The so-called cold splicing is the opposite of welding, which refers to the mechanical splicing of optical cables through “cold splicing”. The entire splicing process can be completed within 2 minutes.

With the rapid development of FTTH(fiber to the home), the demand for optical fiber cold splices has also greatly increased.
