What's the theoretical max bandwidth in LEO's near-vacuum? Could we use a wide 1GHz-1THz channel for directional beams to hit 1Tbps, given a decent SNR?

Cosmic dust and H atoms seem like non-issues for 1000km links? Would power or thermal reqs be an issue here?

I understand it's only about satellite-to-satellite, but still it's interesting.
