We all know that the optical module is a relatively sensitive optical device, and a few users say that the temperature of the optical module increases during use. So why does the optical module heat up?
According to the working temperature, the optical module can be divided into commercial grade and industrial grade, among which the commercial grade optical module is the most widely used. But in fact, different application environments need to choose the optical module corresponding to the temperature level; otherwise it is easy to cause abnormal temperature of the optical module, thus affecting the normal use. So how do you make the right choice between common commercial and industrial grade optical modules?

Commercial grade optical module is suitable for indoor data center room -- because the working temperature range of optical module required for internal interconnection of data center is relatively small (the national policy stipulates that the indoor temperature of the room should be controlled at 22±2℃); And the reliability of the optical module is not high, so the room of the indoor data center can choose the commercial optical module.
Industrial grade optical module is suitable for industrial Ethernet and 5G front-haul -- Industrial Ethernet has a wide operating temperature range and requires high safety and reliability. In order to ensure normal operation of optical module, industrial grade optical module is the best choice. Meanwhile, in the white paper of 5G bearing optical module, it is mentioned that 5G front-haul AAU side optical module involves outdoor application, outdoor temperature is changeable, and the working environment is relatively harsh, therefore, industrial-grade optical module with better performance is needed.
Industrial-grade optical modules are manufactured in strict accordance with industrial standards, with large temperature difference, higher stability and lower power consumption, and meet the requirements of industrial Ethernet network connection.
In addition, the selected optical module is not compatible with the device. Before purchasing the optical module, I did not fully understand the information of the optical module supported on the equipment (such as switch, optical transceiver, etc.), such as the rate and model. Or use A replacement but buy B module.
Besides the reasons mentioned above for the selection of optical modules, the temperature rise of optical modules will also be affected by the unqualified heat dissipation conditions in the environment where the optical modules are located. Such as, there is no cooling device such as air conditioning and temperature and humidity controllers in the machine room -- the use of air conditioning and temperature and humidity controllers can effectively control the temperature of the equipment working environment in the machine room, so as to ensure that the actual application of the optical module environmental temperature is controlled within the range.
Optical module inserted into the device, such as poor heat dissipation function, collocation of no air damper, or switch the front panel without an open design, etc., will affect the switches its own heat, heat dissipation performance is poor, if switch to work long hours will cause equipment temperature is too high, which affect the temperature of the optical module.
Is why optical module temperature rises above the entire contents of the, optical module temperature in addition to the above two reasons, will be influenced by some daily improper operation, such as, pollution of optical module end not clean use directly or use optical module is not do electrostatic protection work, which will cause optical module fault, which leads to temperature rise of optical module.
