I believe they are using lasers derived from shark eyes. Those work better in
space.

Speed of light in glass varies but it’s about 80% of vacuum. Density matters!
Or is it matter makes density? If your dense does it matter? If you're not
matter does that give you energy?

I think he means bandwidth as opposed to "speed". Surely latency would be
almost indistinguishable. However, there could be a lot of difference in the
bandwidth. Regardless of the sat-to-sat speed, the downlink/uplink will still
be the gating factor.

What's the difference in speed between the laser and RF links?

Not what I read. The early sats (the ones other than the first 60) do not
have the laser communications between them, but they do have an RF link between
them. They are functional.

The sats that are up there now also are not equipped to communicate
with each other. There is no inner satellite communication. Everything has to
come down to ground stations right now.

SpaceX got another 60 Starlink sats into orbit this morning. That
brings
the functional constellation to 180 sats. The first batch of 60 don't
count since they are not equipped to communicate with each other.
Various reports say either 300 or 400 sats are required to get a
basic
minimal functioning system. At the rate they're going, this may mean
they will have achieved their goal in another couple of months (they
want to do 2 launches per month).
