I have a broadband connection in France (SFR Red) - I’d like to replace the SFR “box” with a Bpi-R4 running OpenWRT because a) the default SFR solution has only 1GbE LAN ports and I’d like to be able to get the full 2Gbps of the WAN link to individual devices and b) I’d like a suitably low power device I can leave on continuously to use for remote backup from the UK.
I bought a GPON “stick” from this AliExpress listing - supposedly already flashed with OpenWRT and with 2.5Gbs SGMII enabled. I have it plugged into the sfp-wan port on one of my bpi-R4’s running OpenWRT 25.12.5
So, the dumb question is - how do I configure the network interface to talk to it? It is detected when plugged in, the interface reports switching to 2.5Gbps, I don’t see any kernel messages about tx_fault but I can’t talk to it.
The documentation says that it shows up as 192.168.1.10 or 192.168.2.10 - it doesn’t respond if I set the sfp-wan interface to an address in either of those networks. If I tcpdump the sfp-wan interface (it’s not and I can’t do that for a couple of weeks) I don’t see any activity.
ISTR seeing a comment that these ONUs don’t enable their Ethernet interface unless they are connected to the optical network - anyone knowif that is the case generally?
