Ara, the industry's first 3nm PAM4 optical DSP, builds on six generations of Marvell leadership in PAM4 optical DSP technology. It integrates eight 200 Gbps electrical lanes to the host and eight 200 Gbps optical lanes, enabling 1.6 Tbps in a compact, standardized module form factor. Leveraging 3nm technology and laser driver integration, Ara reduces module design complexity, power consumption and cost, setting a new benchmark for next-generation AI and cloud infrastructure.
"Ara sets a new industry standard by leveraging advanced 3nm technology to deliver significant power reduction, driving the volume adoption of 1.6 Tbps connectivity for AI infrastructure," said Xi Wang, Vice President of Product Marketing for Optical Connectivity at Marvell. "With a co-optimized companion TIA, our next-generation PAM4 optical DSP platform empowers customers to scale generative AI and large-scale compute applications with best-in-class performance and unmatched energy efficiency."
"Ara is another Marvell optical connectivity industry-first solution, delivering the power efficiency required for the most demanding AI workloads," said Osa Mok, chief marketing officer, InnoLight Technology. "The Ara platform combined with InnoLight's advanced high-speed optical transceiver design and manufacturing expertise, offers the industry a state-of-the-art pluggable module optimized for next-generation AI and cloud infrastructure."
"We anticipate unit shipments of PAM4 DSPs will more than triple from 2024 to 2029 to nearly 127 million units a year and remain the primary optical technology for connecting assets inside data centers for the foreseeable future," said Bob Wheeler, Analyst at Large, LightCounting. "Ara marks another first for Marvell and demonstrates that PAM4 technology continues to evolve to meet the challenges of AI infrastructure."
Optimized for next-generation AI and cloud infrastructure, Ara is designed to support high-density 200 Gbps I/O interfaces across switches, network interface cards (NICs) and XPUs, while ensuring backward compatibility with prior generations. With best-in-class power efficiency and integration, Ara addresses the growing requirements of hyperscale data centers, to deliver high-performance accelerated infrastructure with best-in-class total cost of ownership (TCO).
