<div class="">As has already been mentioned, I did mean optical
waves. Comes from my perspective as a network guy who uses lots
of optical transport and DWDM systems. Realized I should have
been more specific about optical waves, especially in this
forum. Even more specifically, “waves” are generally a product
provided you by someone else who lights the fiber for you. In
this case, probably Zayo, Lumen, Crown Castle, and maybe even
Google operating the fiber. Generally 10G waves, or some
multiple there of, although 100G waves are out there, and 400G
are coming/testing/just entering production. </div>

<div class="">In this case, I suspect it means 10G waves given the
currently estimated capacity of the ground stations. Moving to
dark lets them do Nx10G links more cost effectively, or 100G
link if the distance is short enough (around 100km at the moment
before you have to go to the much more expensive coherent
optics). And you can do you own support and monitoring, which I
got the impression was part of their problem with Google’s NOC.</div>

Thanks for that - I know them by a different term here but maybe I'm
just not up with the play ;-) I know what you mean. That said, a
single 10G circuit wouldn't even feed a fully loaded bent pipe Gen 1
Starlink bird, so I could imagine that with several birds being
trackable by each ground station, those 100G links and higher will
be hot property.<br>
