Which factors cause the optical module temperature to be too high or too low?
1. The quality and workmanship is poor
If the optical modules’ quality and workmanship are rough, then it is more common to produce optical module temperature anomalies. Because the performance of such optical modules is unstable, the heat dissipation is also poor.
In order to reduce the temperature anomalies and unnecessary losses, it is suggested to use good performance, quality and workmanship modules.
2. Using environment is very bad
Optical modules are mainly used in data centers, computer rooms or switches. If applied in other environments, changes in the ambient temperature will change the optical module temperature; the optical power and optical sensitivity are also affected.
Warm reminder: If the using environment of optical module is bad, it is recommended to choose optical module with industrial temperature or extended temperature.
3. Used optical transceiver
The temperature range of new optical module is usually 0-70 degrees, and the used optical module cannot be reached. Therefore, in the environment of too high or too low temperature, the used optical module cannot work properly. It is recommended that you use the new optical module.
