What we know

PsiQuantum has created an eight-port optical switch that uses its photonics expertise to reduce light loss in data center networks. 2 dB of light loss, which is significantly lower than the 3 dB loss generally accepted in data centers. This technology is designed to enhance the performance of AI data center GPU networks by enabling more efficient optical data routing.

Why it matters

PsiQuantum’s optical switch could improve the speed and efficiency of data transfer within AI-focused GPU networks by minimizing signal loss. Lower light loss means less signal degradation, which can lead to faster communication between GPUs and potentially reduce energy consumption. This advancement may help data centers handle the increasing demands of AI workloads more effectively.

What is still unknown

No independent tests have verified the switch’s performance or accuracy. Details about software compatibility, supported protocols, and commercial availability have not been disclosed. The timeline for broader deployment or integration into existing data center infrastructure remains unclear.
