Marvell Demonstrates Industry's First End-to-end PCIe Gen 6 Over Optics for Accelerated Infrastructure at OFC 2025
Rhea-AI Summary
Marvell Technology (NASDAQ: MRVL) and TeraHop have demonstrated the industry's first end-to-end PCIe Gen 6 over optics solution at OFC 2025. The breakthrough showcases PCIe signal transmission between root complex and endpoint across 10 meters of TeraHop OSFP-XD active optical cable using Marvell's Alaska P PCIe Gen 6 retimer.
The collaboration enables low-latency, standards-based AI scale-up infrastructure by extending PCIe reach beyond traditional electrical limits. The solution incorporates PCIe Gen 7 SerDes technology running at 128 GT/s through TeraHop's linear-drive pluggable optical module, ensuring reliable high-speed connectivity between AI accelerators, CPUs, CXL-pooled memory, SSDs, and NICs.
This advancement is important for next-generation accelerated infrastructure, addressing the exponential data growth driven by AI workloads that demand higher bandwidth and longer reach capabilities.

Protocol-level PCIe Gen 6 Over 10m Optical Cable and PCIe Gen 7 SerDes Over Optics in Collaboration with TeraHop for AI Server Scale Up
As AI workloads drive exponential data growth, PCIe connectivity must evolve to support higher bandwidth and longer reach. The Marvell®
Marvell and TeraHop will demonstrate the industry's first successful transmission of PCIe Gen 6 signals between the root complex and endpoint across 10 meters of TeraHop OSFP-XD active optical cable using the Alaska P PCIe Gen 6 retimer integrated into a TeraHop-developed PCIe Gen 6 retimed riser card. By retiming and converting PCIe Gen 6 electrical signals into optical data, this solution ensures reliable high-speed connectivity between AI accelerators, CPUs, CXL-pooled memory, SSDs, and NICs, unlocking new possibilities for AI-driven data centers.
Driven by an ever-increasing demand for AI, the industry is expecting the PCIe Gen 7 standard to be finalized this year. The companies will also demonstrate PCIe Gen 7 SerDes running at 128 GT/s transmitting signals through the TeraHop linear-drive pluggable optical (LPO) module providing a migration path to standard-based low-latency and high-performance connectivity solution.
"As a leader in high-speed optical interconnects, TeraHop has established a long-standing collaboration with Marvell that continues to drive industry adoption of cutting-edge, high-speed connectivity solutions," said Rang-Chen Yu, Vice President of Marketing, TeraHop. "This breakthrough demonstration of PCIe Gen 6 over optics highlights the potential of optical interconnects in AI and hyperscale infrastructure."
"Marvell continues to lead the industry with the first end-to-end PCIe Gen 6 over optics solution, delivering the critical interconnect technology needed to scale up AI infrastructure," said Xi Wang, vice president and general manager, Connectivity Business Unit at Marvell. "With our strong leadership in PAM technology, generational expertise in PCIe progression, and custom accelerated infrastructure silicon, we enable hyperscalers to optimize their AI architectures for maximum performance, efficiency, and scalability."
