Xsight Labs X2 Switch: Powering SpaceX Starlink V3 in a Milestone Win
There's a networking startup that Patrick can't stop talking about, and it's Xsight Labs. This company, backed by industry giants like AMD, Intel Capital, and Marvell, has just achieved a significant milestone by providing connectivity for SpaceX's Starlink V3 satellites. The star of this achievement is Xsight Labs' X2 switch, a chip we've previously covered in detail (https://www.servethehome.com/xsight-labs-x2-12-8t-network-switch-goes-universal-edgecore/).
Let's break down the X2 switch's capabilities. While many new switches boast speeds of 51.2Tbps or higher, the X2 switch is a more modest 12.8Tbps. This places it in a different category compared to the large-scale AI cluster builds that Broadcom and others are focusing on. The X2 switch is a compact, sub-200W chip manufactured using TSMC's N5 process, setting it apart from the massive AI data center switch chips.
The big news today is that this chip will be used in SpaceX's Starlink V3 satellite, enabling terabit-per-second scale networking in space. Space presents unique environmental challenges that differ significantly from typical data center networking. Additionally, maintaining a satellite's serviceability is unlike any data center scenario. You can't simply submit a ticket to have a switch replaced within an hour while it's orbiting Earth.
The SpaceX team's decision to choose the X2 switch required confidence in its reliability and performance in the harsh conditions of space. Xsight Labs' X2 chip will play a crucial role in meeting the terabit routing needs of the next generation of Starlink satellites, according to Michael Nicolls, VP of Starlink Engineering at SpaceX (https://www.businesswire.com/news/home/20251211121773/en/Xsight-Labs-X2-Switch-to-Enable-Next-Generation-Starlink-Satellites-and-Deliver-Gigabit-Connectivity).
This achievement is a significant win for Xsight Labs, given the high-profile nature of the Starlink V3 deployment. With the growing interest in AI data centers in space, this partnership could signal the emergence of a new field in space networking, with Xsight Labs potentially becoming an early leader. It's exciting to witness these technological advancements and their real-world applications.
Stay tuned for our upcoming series on Xsight Labs' E1 800G DPU, a 64-Arm Neoverse core DPU, which promises to be just as fascinating.
