Photonic Resource Unit (PRU) 2500
Photonic power. Maximum density.
Built for Density
The PRU 2500 (Photonic Resource Unit) is a high-density PCIe Gen5 chassis designed to give data centers direct control over how accelerated resources are built, connected, and scaled. By combining high device density with an integrated photonic fabric, PRU 2500 enables composable, workload-driven infrastructure—without overprovisioning or vendor lock-in. Built for AI, HPC, storage, and financial computing, PRU 2500 delivers performance, flexibility, and efficiency in a single, future-ready platform from Corespan.
