Usually, the ports of the newly purchased optical modules are clean, and there is no need to clean the ports, but for the optical modules that are idle or have not been inserted into the dust cap in time, when they are used again, in order to prevent the transmission performance from being affected, we still have It is necessary to clean the port of the optical module first. Then the following ETU...
