  • What scenarios are industrial optical modules used in?
    What scenarios are industrial optical modules used in?
    • August 24. 2021

    According to the working temperature range, optical modules can be divided into commercial (0℃ - 70℃), expansion (- 20℃ - 85℃), industrial (- 40℃ - 85℃). Generally, only commercial optical module is needed for indoor optical module, but industrial optical module is needed if the optical module is used in outdoor environment with uncertain and fluctuating temperature (such as remote mountain area, ...
