I have a few SFP modules I tried, and the one which works and connects is this:
Fiberstore SFP-1G31-10
This seems to be an older out of sale module, and not available any more, my guess is the newer module will work too: https://www.fs.com/products/12622.html But it’s only a 1Gig module, not a 2.5Gig.
These ones I tried and they don’t work:
- Fiberstore DSFP-10G31-10 10G: This is understandable, this is a 10G only module, and Omnia/MOX supports 2.5G max. Older out of sale model, the new model is
https://www.fs.com/products/11555.html - Fiberstore 10GSFP-PC-30-0.5 10G: This is a 10G DAC cable. Out of sale older version of https://www.fs.com/products/40109.html I’m pretty sure the newer version I linked won’t work either.
- OCLARO TRF5916AVLB643 2.5G: I bought this to connect my Omnia with my MOX on 2.5G so disappointed it doesn’t work. https://ebay.us/a0Zcun
- Compufox AGC761 1G/2.5G: Disappointed again, hoped it would work at least at 1G speed, but it does not connect at all. https://www.amazon.com/dp/B00GUM7R2G/
Please note that seeing messages in dmesg about the SFP module being detected does NOT mean it will work. All modules I tested were detected in dmesg, but only 1 was actually be able to bring up the link.
I still haven’t found any SFP module which would work at 2.5G speed.
All of these were tested with the default Here Be Snails (Stable) branch. And as suggested above the HBD branch with the newer kernel might work. But I don’t want to switch my Omnia to the HBD branch because I depend on it, so I’ve ordered another MOX and after it arrives I can test between two MOX devices with the HBD branch. I’ll update when it arrives.
