That was a very eye-opening post, full of very interesting details on how modern wired networks work, between NIC and the physical layer... so many mysteries about SFP black magic just falled into place in my head...
Thank you! I had to stop digging at some point, but honestly I can't wait for someone to port Doom to a ONU.

I also enjoyed the writing style, and so went and read another article on the blog.
I tried to do something crazy. I had a 4-port XMC 10Gb NIC in the flight computer for a balloon experiment. Two ports of which were used for 10 Gigabit links to an FPGA for data acquisition. I wanted one port to be 100-BaseFX. Turns out that it was not possible to get a compatible SFP module (ok, it's sort of crazy to use a 10 Gb NIC for a 100Mb connection, but the copper RJ45 transceivers all work fine!).
