Nice...8x300Gbit optical beams; that's awesome.

Well put; 1kM is a giant leap from .1Km, but its a far cry from rural transport.
I wonder what
Well put; 1kM is a giant leap from .1Km, but its a far cry from rural
transport.
I wonder what the fixed mobile/metro use cases might look like; Alternate
path, aggregate short distance media backhaul...
I think I like the idea most for non-earth atmosphere use cases, space
vehicle or exploration
I disagree.
It's not the near field stuff that is an issue.. It's the far field stuff
further down the road that is going to murder the link.. Look at his Fig 1
and Fig 2.
Fig 1 is saying that he is getting killed at 50mm/h of rain at 60 gig and
at 175 gig. Fig 2 is saying that everything works

Not quite as bad:

The ~ 50 mm/h rain they seem t
These links are impressive, but I think this kind of stuff was designed for
outer space.

By not working. At those frequencies you're talking a light moisture pocket

Congrats! How does 240Ghz react to atmospheric conditions other than "clear
skys?"
