Ethernet Switches in Space | Xsight Labs

Why It Matters

The deal validates Xsight’s technology for high-reliability, mass-produced space networking and positions the company to capture substantial revenue as Starlink expands its fleet; it also signals a shift toward more software-defined, remotely upgradable satellite architectures.

Summary

Xsight Labs has its programmable, power-efficient Ethernet switches selected for SpaceX’s Starlink Gen 3 satellites, with multiple switches per satellite slated to launch in large volumes this year. The company won a competitive evaluation focused on programmability, power efficiency and resilience to vibration, radiation and thermal stress, narrowing the field to two vendors. Starlink already operates about 8,000 Gen 2 satellites and expects Gen 3 deployment to be a multiple of that fleet, making this a significant hardware win at scale. Xsight’s solution addresses the need for remote programmability and health monitoring in spacecraft that cannot be serviced post-launch.

Original Description

Surviving radiation and thermal stress is the ultimate test. With thousands of satellites already up, the new Starlink Gen 3 fleet is launching with multiple Xsight Labs switches per unit to handle the "extremist edge." #AIIFD4
