Key Developments & Data
Marvell Technology has announced it will showcase industry-first 2nm optical interconnect demonstrations at the European Conference on Optical Communication (ECOC) 2026 in Málaga, Spain.
The company's expanding 2nm connectivity portfolio includes optical PAM4, coherent-lite PAM4/IMDD, and ZR/ZR+ coherent solutions.
These technologies are explicitly designed to support AI data center architectures scaling from 1.6T to 3.2T and beyond by increasing bandwidth density while drastically cutting power per bit.
This launch follows Marvell's previous hardware milestones, including the 5nm 200G/lane 1.6T Nova DSPs in 2023 and the 3nm 1.6T Ara platform in 2024.
“AI data center operators need optical interconnect technologies that deliver higher bandwidth, lower power and greater security across every part of the network.” — Xi Wang

Zubiqo Strategic Assessment
Primary Impact
Hyperscalers and cloud data center operators managing enormous power constraints and bandwidth bottlenecks for large-scale AI accelerator deployments.
Strategic Shift
The aggressive node-shrink timeline for optical interconnects (from 5nm in 2023 to 2nm in 2026) reflects the severe physical limits of power consumption in modern AI infrastructure.
The Ripple Effect
Competing infrastructure semiconductor firms will be forced to accelerate their own sub-3nm optical development roadmaps to maintain parity in the upcoming 3.2T data center upgrade cycle.
