“SpaceX’s laser system for Starlink is delivering over 42 petabytes of data for customers per day, an engineer revealed today.”
SpaceX runs 9,000 lasers between satellites at up to 100Gbps a link with over 99% uptime. That lets Starlink route around ground stations over oceans and Antarctica. SpaceX builds about 200 laser units a week from off-the-shelf parts. Low orbit is now one company’s private backbone.
