And just to be clear when TM stated CWDM and DR4 that to me indicates they are doing both because FR4 is a CWDM product. So don't assume they are not doing both in 400G. But the bottom line is they will build what the customer wants

So  Godo do  you get it  are do you need more explanation.  

Take your shots while you can buddy because I think your time here is coming to an end.
