until no packets are lost in a short period (you can ping the peer device on the UA5000 to check
the packet loss). Note that the adjusting process should be performed stably and slowly.
Step 5 Unplug the patch cord of the detected port, connect the unplugged patch cord to the optical power
meter, and record the input optical power of this point through the optical power meter.
Step 6 If the detected optical power does not meet the technical requirement (for detailed technical
specifications, see the following table), check whether the detecting wavelength set for the
optical power meter is consistent with the working wavelength input by the detected power. In
addition, check whether the optical port is connected tightly.
Step 7 If the detected value meets the technical standard, resume the fiber connection of the detected
port.
----End
Result
The input optical power of the detected port meets the technical requirements.
