Chip Talk > Marvell's Next-Gen Interconnects Accelerate AI Data Center Evolution
Published September 29, 2025
In the rapidly-evolving landscape of AI data centers, Marvell Technology Inc. has emerged as a pivotal player driving unparalleled advancements in interconnect technologies. At the European Conference on Optical Communication (ECOC 2025), Marvell showcased its comprehensive interconnect portfolio, designed specifically to meet the growing demands of AI-driven infrastructures.
The rise of generative AI technologies and expansive AI models has fundamentally changed data-center architecture. These changes require interconnect solutions that deliver on performance, bandwidth, and power efficiency. Marvell recognizes this trend and is tackling these challenges head-on with its full-stack approach, integrating advanced silicon platforms, chiplet architectures, and cutting-edge optical technologies. Their initiatives promise to unlock unprecedented performance, reduce latency, and enhance power efficiency across AI and cloud infrastructures. Discover more in their official details.
One of Marvell's key innovations is the development of co-packaged optics (CPO), capable of supporting 200G/lane connectivity. CPO facilitates energy-efficient, high-bandwidth connections that span multiple racks within AI scale-up domains. This leap in optical technology not only enhances connectivity but also significantly reduces the overall carbon footprint of data centers, a priority for sustainability-focused enterprises.
A highlight of Marvell's ECOC showcase was the introduction of their 800G ZR/ZR+ modules. These modules promise up to 2000km transmission, making them key enablers of scalable data-center interconnects (DCI) over vast distances. As AI clusters become geographically diverse, such long-range capabilities are indispensable for efficient data processing and storage across various sites.
Another noteworthy innovation is Marvell's 200G/lambda 1.6T PAM4 optical interconnect. This technology, incorporated in the Marvell Ara series, brings the transformative potential of a compact, 3nm PAM4 DSP. This enables rapid deployment of AI scale-out fabrics throughout data halls, essential for the future-proofing of AI architectures.
As AI applications continue to proliferate, Marvell's innovations are set to redefine what's possible in data centers. Through presentations and in-depth discussions, Marvell's experts explored the nuances of scaling AI infrastructure, emphasizing efficiency and scalability.
