hi alistu,
this is important discussion(as FEC has strong impact on BER)
after simulation of any my design when we click in BER analyzer its shows some quality factor or BER.
then if we go for report of the simulation there we see the BER after FEC at user definer instant .
the two are same.
therefore i thought the optisystem itself adopts the FEC.
please reply for further discussion.
with regards
