Optical modules can be divided into commercial grade (0 ℃ - 70 ℃), expansion grade (- 20 ℃ - 85 ℃) and industrial grade (- 40 ℃ - 85 ℃) according to the operating temperature range. Generally, only commercial optical modules are required for indoor optical modules. However, industrial optical modules are required if optical modules are used outdoors in harsh environments with uncertain and fluctuating temperatures (such as remote mountains in the wild, tunnels, etc.). Next, ETU-LINK will introduce what features the next industrial optical module needs.
1. The chips and lasers used in industrial optical modules can work normally at - 40 ℃ - 85 ℃.
2. Industrial grade optical module adopts thermal silica gel for physical cooling, so that the laser can dissipate heat quickly.
3. In order to ensure that the industrial optical module can work normally in the low temperature environment, it needs to have the temperature compensation function. The work of temperature compensation is more complex, and it takes technicians a lot of time to calculate and write to achieve a stable temperature fluctuation of the optical module.
4. High and low temperature aging tests are required for industrial optical modules.
5. Industrial optical modules must be designed with scene hardened components in terms of electrical components, enclosures, etc., to ensure the service life of the module.
Industrial optical modules can be divided into industrial SFP optical modules, industrial SFP+optical modules, industrial XFP optical modules, industrial CWDM optical modules, industrial DWDM optical modules, industrial SFP28 optical modules and industrial QSFP28 optical modules according to different packaging types.
