PsiQuantum shows prototype optical circuit switch for AI data center networking
Overview
PsiQuantum says it has shown potential customers a prototype optical circuit switch that routes light signals from GPUs across data centers without converting them to electrical signals.
The company says this would let separate server racks operate as one, with data moving between racks at the same speed and latency as within a single rack. Semafor reports the claims but the prototype's performance is not independently verified in the report. Semafor also says Google is the only hyperscaler it names as using purely optical circuit switching in an AI data center, using MEMS mirrors.
