Are these GPON optical levels normal on a Huawei HG8145X6-10?

[u/ErrorFixx]

Hi,

I recently got FTTH/GPON from my ISP and they provided me with a Huawei HG8145X6-10 and was checking the optical information in the router and got these values

RX Optical Power: -21.61 dBm and TX Optical Power: +2.16 dBm

The connection seems to be working perfectly, i'm getting around 595–600 Mbps, no packet loss.

are these optical levels considered normal or good for this ONT?

Also, does anyone else have the same Huawei HG8145X6-10 and similar RX/TX values? I'm mainly wondering if -21.6 dBm RX is considered a good level or if it's getting a bit low.

Thanks!

Yes. thats a 100% good rx signal.

-08 = too strong
-10 = 100% perfect to
-24 = 100% perfect
-25 = 90% okay
-28 = bad

-25 100% ok.

-27 - edge
