Of course there are limits to this, as FEC is hop-by-hop, so in
long-haul you'll know about circuit quality to the transponder, not
end-to-end. Unlike in wan-phy, OTN where you know both.
Technically optical transport could induce FEC errors, if there are

The frames in FEC are idle frames between actual ethernet frames. So
you recall right, without FEC, you won't see this idle traffic.
It's very very good, because now you actually know before putting the
