DP83843: Optical 10M and LAN conversion

Tool/software:

Hi team,

I would like to use the following configuration.

- Optical 10M → FPGA (MAX10) → differential output (AM26C31QDG4) → pulse transformer → DP83843 (49 and 50 pins) → DP83843 (73 and 74 pins) → LAN connector [AUI to TP conversion]
- LAN connector → DP83843 (65 and 67 pins) → DP 83843 (43-pin, 44-pin) → pulse transformer → comparator (zero-cross detection) → FPGA → optical 10M [TP to AUI conversion].

Is this feasible?
Also, is it possible to realize optical 10M⇔LAN conversion with only one DP83843?
Or, is it necessary to install two DP83843s and divide the functions as follows?
- For AUI→TP (optical→LAN)
- For TP→AUI (LAN→Optical)

Best Regards,
Ryu.
