A high-quality optical module can ensure the flexible operation of high-density optical network, and provide convenience for subsequent management and expansion. So how should we judge the quality of optical module? Next, ETU-LINK will give you some judgment indicators.

The optical module shall comply with MSA multi-source protocol, and the manufacturer shall pass CE, ROHS, FCC certification, etc. the multi-source protocol (MSA) standard specifies the interface and size of the module. The module manufacturer can provide the optical module with the same function as the switch brand according to this protocol, and ensure that the optical module can accommodate a variety of original equipment.

The optical module should have DOM / DDM function, so that users can monitor the real-time parameters of the optical module. The specific parameters include working temperature, working voltage, working current, transmitting and receiving optical power, etc. in addition, it can also display the factory information of the module and prompt alarm / warning.

Before shipment, the optical module needs to be switching test to ensure that the optical module has good quality, performance and compatibility, avoid network interruption, and save maintenance time and cost. It is recommended to ask the supplier before purchasing the optical module.

Check the surface of the module to see if there is any damage, and the golden finger is scratched. If there is obvious damage, it indicates that the optical module may be defective or second-hand goods.

It can be judged by after-sales service, the service life of general optical modules is about 3 years, so we choose the optical module suppliers with quality assurance when selecting optical modules. The optical modules produced by the professional optical module manufacturers of Yitian optical communication provide 3-year warranty.

Use the optical power detector to test whether its optical power is consistent with the parameters in the data manual. If the difference is too large, it is a second-hand optical module.

The above is the way that ETU-LINK teaches you how to judge the quality of optical modules. As a professional optical module manufacturer, ETU-LINK will carry out product appearance test, parameter test, compatibility and connectivity test and optical end face cleaning before leaving the factory to ensure that users get high-quality optical modules.
