Home / Huawei optical module low power
Check whether an optical module that is certified for Huawei data center switches is installed on the optical interface. In addition, use a dust cap to cover the optical bores of an idle optical module.
If the transmit optical power remains low, replace the optical module or install it in another optical interface to check whether it is faulty. If the original optical module is faulty, replace it with a normal
