Keeping flying satellites connected with lasers

To make space-based AI work, thousands of chips must communicate across a vacuum orbit with minimal delay, orbiting in a highly connected constellation.

Without physical cables, we use lasers fired between satellites to transfer information; the equivalent of hitting a moving, coin-sized target from kilometers away, over and over again.

In this video, Google researchers explain how they achieved an 800 Gbps bidirectional laser link by adapting off-the-shelf fiber optics.
