According to the working temperature of the optical module, the optical module is divided into industrial-grade optical module and ordinary optical module. The main difference between the two is the working temperature of the optical module, which is an important parameter affecting the whole optical module. So what's the difference between industrial light modules and ordinary light modules?
The working temperature of ordinary optical module is 0~70℃, and that of industrial-grade optical module is -40℃~85℃. In terms of hardware, industrial-grade optical module is also better than that of ordinary optical module, which is suitable for network deployment in harsh environment.
Ordinary optical module is the most widely used product in the market, which is often used in the environment of data center, switch, network card, machine room, etc. The temperature range of ordinary optical module chip TO CAN withstand is 0~70℃. The industrial-grade optical module is mainly used in harsh environment, and the operating temperature difference is large. The industrial-grade optical module to-can must meet the temperature requirements of minus 40 ° c and above 85 ° c.
Ordinary light module aging test at room temperature, high temperature can only withstand 70 degrees, the ideal operating temperature is 0~70℃; Industrial grade light modules are tested for high and low temperature aging. The highest temperature can withstand 85 degrees, and the modules can work stably in the environment below 0℃.
When the industrial-grade optical module is operating in the low temperature below zero, in order to ensure its performance is not affected, the temperature compensation software must be imported into the industrial-grade optical module to control the stable working current supply of the optical module, so as to ensure the normal operation of the industrial-grade optical module in the low temperature. The work of temperature compensation is complicated and takes a lot of time to calculate and write. This is the main reason why the price of industrial-grade optical modules is higher than that of ordinary optical modules.
