Hello,
Happy new year,

I want to make a shematic who transform ethernet signal in SFP signal (LVEPCL) for exemple in Tx and in Rx i want to transform SFP in Ethernet. I understand if there are lots of ship for this. I want to find a way simple without uC if is it possible.

I want to try this way:
RJ45 (8-pin) → Magnétique Ethernet → PHY KSZ9031 → RGMII → SFP TX/RX
But I don't understandhow to make my schematic ando ne ship it's ok for make duplex transfer ?
I want make a same that an média converter. Can you explain and help me for find a good schematic ?
