as the thread title suggests differentiation is needed.

"in the CWDM DR4 space, which is where we are producing devices..." (Mika at LD Micro, 9 minutes 48  seconds - slide 8).

So, what (if anything) has happened in FR4? Since you have a much better grasp of the tech, I thought I'd ask you.

u dont need to have any grasp of the tech but maybe u can read the whole sentence as they say cwdm dr4 is most used in china and is set to be a standard there!

maybe read more carefully next time. nothing bad  happened on other strings so far. guess we have a couple verticals developing now.
