Here is a #DWDM mux at the data center - neat thing, it is passive (not plugged in to the wall) and you plug fiber in the Line and the different wavelength light shoot out each “channel”. C35 is a 100G laserbeam!

I think about DWDM, and I wonder what that moment is for AI. One shot learning? Something else?
What happens when you need exponentially less datacenter space/hardware but your business model depends on that not happening? It does feel like a matter of time before we find out.

While this definitely was the case for years (decades?) I believed this stopped being true a long time ago. Guessing sometime in the 2010s?

In fact, a lot of money has since been invested to increase capacity of existing fiber through technologies like DWDM, etc

Maybe isolated routes still though?

imo DWDM is when you start getting into the really cool stuff, optical transport really is a whole world of its own.
