is there any way of implementing the /Aout /Bout from Aout & Bout on the differential board before the 26LS31 ?
Else, how to make the differential interface assuming we only have A & B, 5V & GND (index isn't used by UHU) can i expect any noise elimination this way ?
Thanks !

The original UHU does not use differential signals, so your encoder seems to be OK.
In order to use a differential interface you need then a differential transmitter chip on the encoder side and a differential receiver chip on the UHU side. The interface cable should be shielded twisted pair (with 4 pairs minimum) for best results.
