Does anyone know if it's normal for the RX Optical Power on my ONT/router-combo device (Huawei HG8145V5) to keep getting weaker?
When I had the FTTH service installed on May 1, the RX was at −21.25 dBm, and now it's down to −22.60 dBm.
I've attached the stats page, and, while it's still within spec, it seems odd that it keep dropping every 5 or 6 days or so.
There are only two people on FTTH going from the local fiber cabinet – my neighbor and me, and the neigbhor's RX seems to be steady at about −21.02 dBm.
The only difference in the installation appears to be that the drop cable from the outside termination box is longer on my installation, and is getting slightly more direct sunlight.
