In the field of optical communication, since the working temperature will affect the parameters of the entire optical module, the optical module can be divided into industrial and commercial optical modules according to the different use environment and uses. The difference between the two is mainly reflected in the working temperature that can be used. Then what is industrial and commercial grade? What are the differences between commercial and industrial grade optical modules?
In the field of optical communication, since the working temperature will affect the parameters of the entire optical module, the optical module can be divided into industrial and commercial optical modules according to the different use environment and uses. The difference between the two is mainly reflected in the working temperature that can be used. Then what is industrial and commercial grade? What are the differences between commercial and industrial grade optical modules?
1. Different working environments are available
Industrial grade optical module is used in the industrial production environment of the optical module, because many industrial production environment is not very good, there are extreme temperature and large temperature difference, in addition to the existence of vibration and other adverse factors. However, commercial environment is not the same. Generally, there is a comfortable environment, temperature and humidity are relatively stable, and they are not extreme. Therefore, commercial optical modules usually need to be used in a good and stable environment.
2. The temperature and test method of the chip are different
Normally, the chip of industrial optical module can withstand the temperature from minus 40 degrees Celsius to more than 15 degrees Celsius. During the test, high and low temperature aging test is needed to see the aging reaction under the extreme temperature. However, commercial grade optical modules only need to be tested at room temperature because their chips can withstand temperatures ranging from zero to real degrees Celsius.
3. Different temperature compensation
For industrial optical modules, temperature compensation software must be introduced. Its function is to ensure that the optical module has a stable working current supply. When the temperature changes, the temperature compensation software will take effect. Commercial grade optical modules, which are favored by customers, do not require temperature compensation, so they do not increase material and manufacturing costs.
This is the main difference between commercial optical modules and industrial optical modules. As can be seen from the above introduction, commercial optical modules and industrial optical modules have different applicable environments and different chip temperature tolerance, so the two optical modules can be used in completely different places. If you need to use optical modules, you should choose according to the actual needs.
