Expert Statements
Adit Narasimha, Senior Vice President, Signal Connectivity Group at Astera Labs
“The real question for architects isn't retimer vs redriver, or copper vs optical: it's whether they have one comprehensive toolbox with the optionality to pick the right tool for their evolving reach, density and power requirements”
Adit Narasimha, Senior Vice President, Signal Connectivity Group at Astera Labs
“That is what we built with Aries: the same intelligence and the same software, for the solution the link needs.”
Raghu Nambiar, Corporate Vice President, Data Center Ecosystems and Solutions, AMD
“As AI infrastructure grows across servers and racks, customers need open connectivity options that work with their platform designs. AMD is advancing a broad portfolio of compute and connectivity technologies, and we work with ecosystem partners such as Astera Labs to help customers build flexible, interoperable AI systems.”
Srini Krishna, Fellow, Intel Data Center Group
“As systems continue to scale, reliable high-speed connectivity is essential to keeping compute resources efficiently utilized. Intel’s collaboration with Astera Labs builds on multiple generations of PCIe retimer validation and extends that proven interoperability toward PCIe 7, helping customers design scalable platforms with greater confidence and flexibility.”
Matt Sysak, Chief Technology Officer, Lumentum
“Linear optics works at scale only if the electrical and optical halves of the link are designed together from the start. Pairing our photonic engines with Astera Labs' Aries 7 Smart Optical Driver and TIA lets us hit the reach and density targets that multi-rack AI fabrics need, without the power and latency penalties of a retimed optical module.”
Samuel Liu, Vice President, Product, Lumilens
“An AI cluster is only as strong as its weakest link six months into deployment. Astera Labs' Aries 7 Smart Optical Driver and TIA let us build optical connectivity solutions with links that hold their signal integrity over the full life of a deployment, not just on Day One. That resilience, combined with enabling consistent performance across every unit we build, gives hyperscalers the confidence to qualify our solutions once and scale them across their fleet.”
Zane Ball, Chief Technical Officer, Open Compute Project
“The OCP Signal Conditioner Standard Footprint was built to be protocol-agnostic, and extending it from Taurus's Ethernet and UALink applications to the Aries PCIe portfolio is exactly the kind of industry-wide adoption we hoped to see. One common footprint spanning multiple protocols means hyperscalers can design their boards once and rely on multi-vendor sourcing as their fabrics evolve, instead of re-solving the same integration problem for every new interconnect.”
Purpose-built retimers, redrivers, cable modules, optical drivers, and optical transimpedance amplifiers (TIAs) to support diverse PCIe 7 connectivity in AI systems
News highlights: * Most comprehensive PCIe signal conditioning portfolio: Building on Aries’ field-tested deployments, Aries Smart Signal Conditioning family is now the industry’s first PCIe 7 portfolio to span copper and optical interconnects including retimers, redrivers, cable modules, optical drivers, and optical TIAs. * PCIe 7 connectivity from chip-to-chip, box-to-box, and rack-to-rack: Aries 7 portfolio is designed to enable PCIe 7 connectivity across chip-down solutions, smart cable modules including near package optics (NPO), linear pluggable optics (LPO), and copper—giving customers the flexibility to optimize for reach, power and density for each link in an AI cluster. * Smart, unified link intelligence: Advanced fleet management and deep diagnostics across Aries 7 portfolio is unified under the COSMOS software suite for ease of monitoring, debugging, and dynamic tuning—accelerating time-to-market and improving utilization for deployment at scale. SAN JOSE, Calif., Oct. 08, 2026 (GLOBE NEWSWIRE) -- Astera Labs, Inc. (Nasdaq: ALAB), a leader in semiconductor-based connectivity solutions for rack-scale AI infrastructure, today announced the industry’s broadest PCIe® 7 signal conditioning portfolio spanning smart retimers, redrivers, cable modules, optical drivers, and optical TIAs. The expanded Aries 7 portfolio offers hyperscalers, neoclouds, OEMs and ODMs a comprehensive connectivity platform that now extends reach from centimeters of PCB trace to 50+ meters over optical cables spanning multiple racks.
