**Marvell and TeraHop Unveil First End-to-End PCIe Gen 6 Over Optics at OFC 2025**

On March 27, 2025, Marvell Technology, Inc. announced a breakthrough collaboration with optical solutions provider TeraHop, showcasing the industry’s first end-to-end PCIe Gen 6 over optics at OFC 2025 in Santa Clara, California. The demonstration highlights a successful transmission of PCIe Gen 6 signals across a 10-meter optical link, using Marvell’s Alaska P PCIe Gen 6 retimer integrated into a TeraHop-designed riser card and active optical cable.

The solution offers low-latency, low bit-error-rate transmission while extending PCIe's traditional electrical reach. It is designed to support scale-up infrastructure in AI-driven data centers, enabling high-speed optical connectivity between AI accelerators, CPUs, SSDs, NICs, and memory using PCIe or CXL protocols.

Additionally, Marvell and TeraHop previewed PCIe Gen 7 SerDes running at 128 GT/s over optical modules, pointing to future standard-based, high-performance, low-latency interconnects. Marvell emphasized its commitment to advancing interconnect technologies essential for the growing demands of AI infrastructure.

Marvell Vice President Xi Wang noted this development as a milestone for scalable AI systems, while TeraHop's VP Rang-Chen Yu emphasized the role of optical innovation in hyperscale data centers.
