Marvell Technology

SerDes is the foundational building block of high-speed networking, present in every XPU, switch, high-speed interface, and optical component in a modern data center. Its performance has a direct impact on power consumption, latency, bandwidth, link length, and ultimately total cost of ownership.

Marvell has doubled the line speed of its leading SerDes approximately every two years. The most recent demonstration of 224G long-range SerDes achieved lane bit error rates of 1e-11 at 4 picojoules per bit across a 2.5-meter CPC-backplane-CPC channel, with up to 512 lanes integrable into a 102.4T switch.

Senior Staff Engineer Aatreya Chakravarti explains how the technology works, where it fits within the broader connectivity stack, and why SerDes leadership remains central to scaling AI infrastructure: https://mrvl.co/44fVLXD

Contemporary silicon photonics modulators are constrained by the diffraction limit of light, restricting their ability to scale efficiently to the bandwidths AI infrastructure will require. Plasmonics offers a path forward.

By compressing light below the diffraction limit at a metal-dielectric interface, plasmonic modulators can operate at speeds exceeding 1 THz, more than 10x faster than conventional photonic modulators, while measuring approximately 10 microns in length, 300x to 500x shorter. The result is exponentially higher bandwidth density within the same silicon photonics platform, without requiring a shift to new material systems.

Marvell Senior Director Claudia Hoessbacher and Director Wolfgang Heni of Optical Engineering detail the technology, its applications across scale-up and scale-across networks, and where development stands today.

In an exclusive interview with DIGITIMES at Computex 2026, Marvell President and Chief Operating Officer Chris Koopmans covered a lot of ground: the company's decade-long transformation into a data infrastructure leader, why securing supply chain capacity is ultimately about trust, and how the transition from copper to optical will unfold over the next five years in scale-up networks.

On the copper wall: "The copper wall will eventually fall." On the ASIC business: it is fundamentally an I/O business, not an XPU business. And on supply constraints: the current environment may actually be healthier for the long-term trajectory of the AI industry than unconstrained growth would be.

One of AI's three big problems is power consumption, which is becoming a hard constraint in AI infrastructure. Data center power limits are tightening, and a significant portion of the energy modern AI systems consume is spent simply moving data between compute and memory.

Marvell Photonic Fabric technology addresses that directly. By integrating optics closer to the XPU, the platform delivers up to 2x greater energy efficiency compared to copper, while also supporting up to 2x more compute within the same power and space footprint.

The same platform extends scale-up clusters beyond a single rack, and enables pod-scale memory sharing across systems. Senior Director of Product Management Uday Poosarla details how it all works together: https://mrvl.co/4g8fq2P

For the 13th year, Marvell employees laced up and ran together, spanning 36 sites across the globe.

The Marvell Global 5K has become more than an annual event. It reflects something true about how this company operates: the work is demanding, the problems we solve are consequential, and we do it as one team, no matter the time zone.

Building the semiconductor infrastructure that powers AI takes endurance, precision, and the kind of collaboration that only comes from a team that genuinely enjoys working together. The Global 5K is a reminder of all three.
Congratulations to every runner, volunteer, and organizer who made this year's event possible across six continents.
