Original ONT you have is from ALU/Nokia (firmware version format points to that vendor).
What is the model ?
my original ONT from SFR ?

Can you somehow dump mibs from that device ?

DHCP only.

We probably need help from @maximushugus who has root access to the same ONT model.
But I don't know if it's the same OLT, so there could be differences.

The only vlan that may work, is 101, but I'am not sure if this is not for management purpose only..
VLAN 101 is probably the right one, which gets untagged by the original ONT.

So internal switch should forward frames outside.
It is strange not to see anything on counters..

If you send DHCP request, can you see anything on PON output ?

the DHCP DISCOVER remain without any answer...0 traffic sent PON side

Ok, so it is not forwarded internally from LAN to PON.

Can you please make a dump of that DHCP packet including all headers ?
some .pcap file ?

Can you please provide me with optical signal level (RX) ?
You can read it via WebGUI.

If there is a situation that it is near sensitivity cut-off, it may be that download goes well, but - on the upload it is bit asymetric.
I mean - it does not mean that if download has no errors, upload has no errors too.
Upload uses different wavelength that have different attenuation properties, and lasers are different with TX power fron ont to ont... (each unit is different).

At least we could say if log signal could be the reason.

With Livebox 5 :
  • Signal RxPower : -18.664dBm
  • Signal TxPower: 2.109dBm

With Leox LTX-010H-D :
  • Signal RxPower : -19.507160dBm
  • Signal TxPower: 2.484155dBm

That is ok. And you also have a problem with uplink speed ? (errors on uplink ?)

Here are different signal power :

1. With original orange ONT Huawei HG8010Hv6
TX Optical Power: 2.16dBm
RX Optical Power:   -16.90dBm

2. With ONT Leox LXT-010H-D
TX Optical Power: 1.109803dBm
RX Optical Power:   -17.099652dBm

I have no problem detected but Is this normal ?

Yes, please check GPON Optics B+ specification, TX is in range.
RX is also ok, you are quite close to OLT.

Hello

I'm really not good at English so I went through Google Translate.

Yes that's it.

My subscription is limited to 600MBit/s for upload speed. I get it when I directly use the livebox 5 with the fiber connected to it :
Fiber <====> Livebox 5 <====> PC

With the LEOX LTX-010H-D (or even with the LTX-010G-D), the upload speed is limited to 7 Mbit/s whether with the livebox 5 or with my OpenWRT router :
Fiber <====> LEOX <====> Livebox 5 (Eth4) (Or OpenWRT Router) <====> PC

By running the command "iperf3 -c speedtest.milkywan.fr -p 9201 -u -b 400M" on my router, I get the following results:

Code: [Sélectionner]
