Hi, I'm currently trying to set up the module in my pcengines APU6. Since I cannot access the web interface: Is this only possible when the SFP is physically connected to the GPON link?

ethtool reports the module correctly:

But link is reported as DOWN:

Hey, we are getting fiber internet and because I am already running a OPNsense firewall in a VM with Intel NICs connected to my switch, my question is, do I have to connect the moduel with a pci-e card (via passthrough) to the VM or could I (ideally) put the GPON module into the SFP port of my NETGEAR switch and have it via a VLAN connected to the NICs/VM/OPNsense interface?

Great project btw.

This PR adds an instruction how to enable 2.5G on the GPON-SFP in case it isn't enabled by default.

The Zyxel PMG3000-D20B SFPs I bought directly from a distributor had a default port speed of 1G and wasn't able to use 2.5G until I configured the speed manually using the CLI.

I wrote up a short guide on how to configure an Ubiquiti EdgeRouter since the part where you first have to access the SFP module's web interface to set the SLID/PLOAM pw, then configure PPPoE on the same interface is not obvious.

Hi, finally i was able to establish WAN with my X520-DA2, the Zyxel Modul in a pfsense box. So technically its works but....

the speed isnt quiet good as expected. i will get only ~800 Mbits on my 1G from "Deutsche Telekom FTTH". The Telekom ONT gives me 1070 Mbits Downstream (thanks telekom for overprovisioning) out of the box. So not even the 940 Ethernet Cap. Is this a problem with my X520 card? Can the X520 handle 2,5 Gbit with this SFP ONT? Unfortunately i cant see if the sfp is running in 2,5G or in 1G Mode.

any clue? experience?

Anybody can confirm compatibility of this SFP module with server/desktop NIC based on Broadcom 57810S chipset?

Dell 0Y40PH or N20KJ
HP 530SFP+
10Gtek 57810S-10G-2S-X8

Is soldering mod needed to get it working in these type of cards?

Is management working when fiber is not plugged in?

1Gbps (SGMII) speed is working with unmodified driver? Anyone tested 2.5Gbps (HSGMII) with modified driver?

Hello,

I use the SFP on a Telekom FTTH connection. The Telekom OLT expects an ONT with the same serial number as the old one that Telekom installed when providing the connection. If I change the serial number of the SPF with the sn command to that of the old ONT, the connection works. However, with each restart of the SFP, the serial number is reset to the initial value at delivery. Does anyone know a way to store the serial number permanently in to the flash storage? Of course I could also initiate a rediscovery by Telekom but I would like to keep the old ONT as a backup and that would then no longer work with its serial number.

Hello, i have the same zyxel gpon.. but the admin/1234 combo don't work as login. Can someone explain how they were discovered in the first place so i can replicate the same tecnique on my module ?

thanks

Having a look around the firmware I found out that there other default credentials besides "admin"/"1234" in the firmware that are used depending on the "customer" "soft feature":

0x12 -> "root"/"integral" 0x13 -> "carbon"/"C@rB1N0x@m1NE" others -> "admin"/"1234"

I don't know which ISPs these two values correspond to, but this may be useful to someone acquiring a non-telekom branded version of the same Zyxel module.
