Understanding Orange Fiber 300 Mb/s Optical Transmission & Reception Power: GPON, ONT, Funbox 3.0

Hello, My name is Marcin and I am new to the forum. For 2 days I have had the Orange Fiber 300 Mb / s service, everything works fine, but I am interested in this topic regarding the optical transmission and reception power.

My results are 1 / -19 (dBm)

I looked around in the subject and read that Terminal ONT in GPON technology, it should transmit the signal on average within +0.5 dBm / +5 dBm and -27 dBm / -8 dBm receiving. Unfortunately, I did not find detailed information about Funbox 3.0, what is the maximum signal sensitivity limit. I suspect Over -30 (dBm).

In the contract, I should not disconnect the FB3.0 from the power supply for the next 10 days in order to optimize the signal. I am curious if these values will change.

Are my parameters correct? and can they be better?

best regards

If the speeds are ok, you have nothing to worry about
As you provide, the parameters are within those you provided for the ONT terminal, probably for FB 3.0 it is similar, after all, the technology is the same ...

I think so too I compared it to the WiFi Analyzer and the signal quality "very good" should not exceed -30 dBm is also oki, considering that the download and upload speeds exceed those offered by ISP. It's just a pity that I can't manually change the MTU to the maximum frame. In my case it is 1500 and FB3.0 is set to 1540.

Before I close the topic, I will give a chance to others who are familiar with the topic
Thank you very much for your answer.

It just has nothing to do with it :)

Is it about LAN? It misses the point, as the sizes of the frames vary, the effect may be counterproductive. In fact, the speed gain will be small anyway, I prefer to leave the default MTU, because you never know what device I will connect to the network. For more switch-server bandwidth, I have the trunking port set, here is the bigger difference.

Oki, got it. Thanks for the clarification. I close the topic
