GPON-ONT for Supermicro X11SDV

[q54e3w]

My Telus service provisions a fibre 1000mbps service via a NOKIA, A G-010S-A fibre to SFP transceiver. Sadly the transceiver is not compatible with the Supermicro motherboard as when I insert it I get a incompatible adapter inserted error. I could bypass their router completely if I can find a transceiver compatible with my Supermicro X11SDV motherboard.

Curious if anyone has any tips as to compatible transceivers I could try, or sources of info for options.

What is the exact error it shows? Where does it show it?

Did you try setting: hw.ix.unsupported_sfp=1
That would need to be in /boot/loader.conf.local

Thank you. No luck sadly.

It would need to be hw.ixl.unsupported_sfp=1 for that NIC.

Though 'unqualified' might be a different error there.

@stephenw10 Thank you. I tried that as well but no joy.

I'm wondering if its to do with supported media type? Any thoughts from below?

Ah, interesting. So it is attaching the driver and seeing the module, and even pulling data from it. Just not linking. Have you tried setting a fixed link speed?

[q54e3w]

@stephenw10 Ah, did some googling and found its an issue with the transceiver trying to sync at 2.5gbps on a SFP port that can only support 1 or 10gbps. Its some GPON thing that a number of folks have been working on, for example here

I may need to add a third party card in if I want to use this GPON SFP module directly.

[stephenw10]

Ah, yes if it's trying to present as 2.5G I don't believe that will work in that NIC. Not without new firmware (that doesn't exist yet).
There are a few threads about that here though IIRC the module was not recognised at all in those cases.
There are some youtube videos demonstrating it....

@stephenw10 I have this exact same model GPON ONT, also from a Canadian ISP. I'm trying to bypass my ISP's device and plug the thing directly into a Netgate 6100, but so far no luck.

Should this thing work in a 6100? Can they negotiate at 2.5? Or even at 1 gigabit would be fine. Would it matter which WAN port I use? Thanks.

[stephenw10]

The ix SFP NICs in the 6100 will not link at 2.5G. Those GPON modules could present as 1G or 10G internally and connect externally at a different speed. Potentially.

What does ifconfig -vvm ix0 show? Assuming it's in ix0.

@stephenw10 I just found a more highly related thread and just 2 minutes before your reply here posted there:
