A large number of optical fiber connection devices are used in the communication system, which are susceptible to contamination during maintenance. When there is dirt on the end of the optical fiber, the loss value of the optical fiber is greatly increased, which affects the quality of optical signal transmission. According to statistics, more than half of fiber optic network failures are caused by contamination of the fiber end face.
There may be many reasons for the contamination of the fiber end face, the common ones are: impurities in alcohol, oil stains on fingers, dust, and condensation residues of water vapor in the air. Don’t underestimate these contaminants. A 9-micron dust is difficult to see without a microscope, but this particle can completely block the core of the optical fiber, thereby affecting the quality of the optical signal, causing the performance of the communication system to decline, and causing the stable operation of the network. Hidden dangers. In severe cases, the entire optical network system may be paralyzed. Therefore, cleaning the end face of the optical fiber is basically an important step when the optical fiber is installed or an abnormal problem is investigated.
