Light module is damaged with common judgment steps.huawei compatible sfp module Production

1. Test whether the optical power is within the scope of the indicator, such as no light or light power.

Approach:

Check the wavelength and measurement unit of the optical power selection (DBM)

Clean the end surface of the fiber connecter, light module light.

C. Check whether the end surface of the fiber connector is black scratched, whether the fiber -fiber connector is broken, and replace the fiber connecter for the exchange test.

d. Check whether the fiber connecter has a small curved.

The hot insertion module can be re -inserted and tested.

f. Test the same port to replace the light module or the same light module replace the port.

Light module is currently a very common photoelectric product in photoelectric products. The light module will be used for weak electricity engineering and room division projects. Effective protection of the light module is not damaged is our job
