Sivers Semiconductors, a leader in photonics and wireless technologies, has announced a strategic partnership with O-Net Technologies and Enablence Technologies to develop an advanced external light source (ELS) module with Sivers' laser arrays. The ELS module is designed to support the rollout of Co-Packaged Optics (CPO) in AI datacenters and high-performance computing systems.

Why it matters

CPO integrates optical elements into GPU and switch packages, delivering high-speed optical interconnects with 80% lower energy consumption compared to copper. The ELS module is a crucial companion to CPO, as it separates temperature-sensitive lasers from the extreme heat of high-power processors, ensuring wavelength stability and enhancing system reliability and serviceability.

The details

O-Net Technologies will serve as the ODM partner, integrating Sivers Semiconductors' laser arrays and Enablence's NxN Star Coupler to deliver a scalable ELS module for scale-out and scale-up optical systems. The ELS module is expected to enable a practical, scalable solution aligned with the needs of high-performance computing and AI datacenters.

  • The partnership was announced on March 17, 2026.
