BeagleBone-Black with fiber (SFP) interface

Hi all -

I’m trying to equip a BBB with a fiber interface. Original idea was to design a custom BBB-based PCB to have a SFP module on-board. I found some old discussion on this topic here https://groups.google.com/g/beagleboard/c/y579ziDQuhU?pli=1, where there was no final solution posted. I also found following part Dynamic Dev Tool Page | Microchip Technology, which seems to come with a software-stack for BBB and is intended to be used with the it.
Anyone developing something similar or has ideas on how to make the BBB fiber-ready?

Cheers,
Oliver
