ONT in Mikrotik ?

Hi,

I have read a lot of threads here but I’m very confused about fact it’s possible or not. Right now I use my Mikrotik router directly connected to an ONT (supplied by my ISP). I have been able to remove their damn proprietary box (in charge of routing and all useless stuffs !).
If I succeed to find the correct SFP module to plug the fiber directly to my Mikrotik box, will Mikrotik firmware be able to emulate and handle all tasks of ONT ?

Thanks,

Vincèn
