5G optical transmission is very important for the management of billions of devices and massive data. At the same time, it also provides the connection speed and high reliability required by users. This means that 5G optical network will need more powerful and stable optical connection
The end surface cleanliness of optical device is very important for 5G optical connection
5G and data center construction speed up, the demand for high-performance optical devices / modules is growing rapidly. No matter building a new network or maintaining an existing network, the end faces of optical fiber cables and optical connectors, demultiplexers, transceivers and other optical devices must be completely cleaned, which includes ensuring that all connections and splices are kept completely clean, so as to avoid potential problems, such as insertion loss (optical signal attenuation), return loss (optical signal reflection intensity), which exceeds the optical path loss budget As a result, the communication quality of the whole optical link decreases or even the network is interrupted. For 5G network, this is particularly important, because in the ultra-high speed optical link, the influence of the same size particle contamination (UM level) on the quality of optical signal communication greatly exceeds people's expectations, and sometimes plays a decisive role in the high-speed, high bandwidth optical network communication.
Optical transceivers, optical connectors and other passive device end faces may be contaminated by various sources, including grease, gelatin, lint, waste gas, moisture or dust. The polluted fiber end can change the refractive index or optical signal transmission path. If the pollution is serious, the change of the refractive angle is enough to make the optical signal completely lost, leading to the interruption of the whole network. The 5G network with faster speed has higher frequency and is more sensitive to the change of refraction angle.
Therefore, in the production and manufacturing process of optical devices, the cleaning and detection of optical fiber end face is an essential process. Taking the production test and detection process of active devices as an example, the optical fiber end face cleaner and end detector are used for cleaning and detection.
