Marvell Showcases Industry’s First End-to-End PCIe Gen 6 Over Optics at OFC 2025

Santa Clara, CA – Marvell Technology, Inc. and TeraHop have announced a joint demonstration of the industry's first end-to-end PCIe Gen 6 over optics solution at OFC 2025. The demonstration showcases low-latency transmission over a 10-meter optical link using Marvell’s Alaska P PCIe Gen 6 retimer, enabling scalable, high-performance infrastructure for AI data centers.

This solution addresses the growing bandwidth and distance needs of AI-driven workloads by converting electrical PCIe signals into optical data. The demo includes PCIe Gen 6 signals traveling between the root complex and endpoint via TeraHop’s OSFP-XD active optical cable, using a custom retimed riser card. It ensures fast, reliable connections among CPUs, AI accelerators, CXL memory, SSDs, and NICs.

Additionally, Marvell and TeraHop demonstrated PCIe Gen 7 SerDes operating at 128 GT/s over linear-drive pluggable optics, highlighting future-ready performance for hyperscale environments.

TeraHop VP of Marketing Rang-Chen Yu emphasized the value of the partnership in accelerating adoption of high-speed connectivity. Xi Wang, VP and GM of Marvell’s Connectivity Business Unit, noted that the demonstration affirms Marvell’s leadership in enabling low-latency AI infrastructure through PCIe innovation and PAM technologies.

The solution is designed to support hyperscaler demands for performance, efficiency, and scalability in the next generation of accelerated data centers.
