Hi, friend!
You can run the display ont optical-info command to query the information about the optical modules of online ONTs connected to a PON port and the optical power of offline or unconfigured ONTs.
huawei(diagnose)%%display ont optical-info
{ frameid/slotid/portid<S><Length 5-15> }:0/3/0
{ all<K>|offline<K>|ontid<U><0,127> }:0
Command:
display ont optical-info 0/3/0 0
