The difference between commercial optical module and industrial optical module

11-08-2020

In the field of optical communications, since the operating temperature will affect the various parameters of the entire optical module, optical modules can be divided into industrial-grade optical modules and commercial-grade optical modules according to different use environments and uses. The difference between the two is mainly reflected in In terms of operating temperature, what are industrial and commercial grades? What are the differences between commercial-grade optical modules and industrial-grade optical modules?


commercial optical module

1, Different working environments can be used

Industrial-grade optical modules are optical modules used in industrial production environments. Because many industrial production environments are not very good, there are extreme temperatures and large temperature differences, and there are also undesirable factors such as vibration. The commercial environment is not the case. Generally, there is a relatively comfortable environment, with relatively stable temperature and humidity, and not extreme. Therefore, commercial-grade optical modules usually need to be used in a relatively good and stable environment.


2, The temperature and test method of the chip are different

Under normal circumstances, the chip of an industrial-grade optical module can withstand temperatures from minus 40 degrees Celsius to 15 degrees Celsius. When testing, it is necessary to perform high and low temperature aging tests to see the aging reaction at the extreme temperature. However, commercial-grade optical modules require only room temperature aging tests because their chips can withstand temperatures ranging from zero to actual degrees Celsius.


3, Temperature compensation is different

For industrial-grade optical modules, temperature compensation software must be imported. Its function is to ensure that the optical module has a stable operating current supply. When the temperature changes, the temperature compensation software will take effect. Commercial-grade optical modules, which are popular among customers, do not require temperature compensation, so materials and manufacturing costs will not increase.


This is the main difference between commercial-grade optical modules and industrial-grade optical modules. Through the above introduction, you can see that commercial-grade optical modules and industrial-grade optical modules have different applicable environments and different chip temperature tolerances, so this The two levels of optical modules can be used in completely different places. If you need to use optical modules, you must choose according to actual needs.
