It is really interesting that pluggables technology is outpacing "not a 
lack of" forwarding capacity, but accessibility.

25.6T (400G) and 51.2T (800G) chips are around in all shapes, sizes and 
prices, but getting a package of ports and a mature NOS in one chassis 
is proving to be quite the challenge when typical network operators need 
to grow beyond 100G, without having to mortgage the cows.

1.6T pluggables should make commercial landfall by Q3'26. I'm not sure 
router/switch vendors will have a compelling offer for operators outside 
of the cloud & content space by then, or even two years out following that.

Mark.
