Achieving Seamless 1.6 Tbps Interoperability for HPC, AI & ML SoCs: A Deep Dive into the Samtec and Synopsys Revolution

In the ever-evolving landscape of high-performance computing (HPC), artificial intelligence (AI), and machine learning (ML), the demand for greater bandwidth continues to surge. Today, 1.6 Tbps Ethernet is not just a benchmark for speed—it's a necessity. But achieving this level of performance requires more than just faster hardware. It demands interoperability across a complex, multi-vendor ecosystem.

In a recent technical webinar, industry leaders Samtec and Synopsys came together to share how their latest collaboration is driving seamless 1.6 Tbps interoperability across systems designed for next-gen AI, ML, and HPC workloads. This blog unpacks the key insights, innovations, and implications for system architects and data center engineers.

The Bandwidth Explosion in AI, ML, and HPC Applications

From AI inference at scale to simulation-heavy research workloads, modern data centers face enormous data throughput demands. To support these next-generation applications, systems must evolve toward 1.6 Tbps Ethernet.

However, this growth in bandwidth brings with it an increased need for seamless, high-performance interoperability. As multiple vendors contribute different components—switches, routers, PHYs, connectors—the challenge becomes ensuring they all work together without performance loss or signal integrity issues. This is why real-world interoperability testing has become critical.

The Role of Interoperability in Next-Gen System Design

Interoperability ensures that diverse components can function cohesively, preventing system failure, minimizing downtime, and maintaining peak performance. For applications involving massive data exchange, even a slight performance drop can have costly consequences.

To address this, Samtec and Synopsys are working on:

• Real-world interoperability testing through plug fests and standard body events

• Early 224G TX and RX compliance characterization with various channel conditions

• Advanced connector and PHY technologies designed for seamless integration

These initiatives help reduce deployment risk and accelerate go-to-market timelines for high-speed systems.

224G SerDes: The Foundation for 1.6 Tbps and Beyond

At the heart of 1.6 Tbps Ethernet lies the advancement of 224G SerDes (Serializer/Deserializer) technology. These architectures are optimized for ultra-fast data transmission with low power consumption and reduced latency.

Synopsys’ 224G PHY IP offers:

• Silicon-proven performance

• Low-power architecture

• Compatibility with a wide range of channels and interconnects

Samtec complements this with its high-density, low-loss Si-Fly® HD co-packaged and near-chip solutions. Together, these technologies deliver a scalable, reliable foundation for both current 1.6T deployments and future 3.2T innovations.

Inside the 1.6T Ethernet Ecosystem

The 1.6T Ethernet ecosystem isn't limited to a single architecture. It comprises a range of components, each optimized for specific deployment scenarios:

• LR (Long Reach) direct-attached cables for extended distance

• Cabled backplanes for modular, high-performance setups

• NPO connectors for dense, short-range interconnects

This diversity enables designers to optimize systems based on real-world operational needs, whether the goal is space efficiency, speed, or cost-effectiveness.

Samtec and Synopsys: A Powerful Partnership for Interoperability

This collaboration between Samtec and Synopsys ensures that system integrators have access to interoperable, production-ready solutions. Their joint commitment includes:

• Rigorous third-party testing for validation

• Standard-compliant 1.6T Ethernet IP from Synopsys

• Next-gen connector technologies from Samtec

The result is a robust, scalable infrastructure that minimizes integration challenges and maximizes performance across complex deployments.

Conclusion: Interoperability is the Key to Future-Ready Infrastructure

As we move toward increasingly complex workloads in AI, ML, and HPC, the need for seamless, high-speed interoperability becomes mission-critical. The work being done by Synopsys and Samtec in 224G and 1.6T architectures sets a clear path forward.

For system designers, engineers, and decision-makers, now is the time to invest in pre-tested, verified, and standards-aligned components that can scale with demand.

Explore the full technical insights shared during the Samtec and Synopsys webinar to better understand how to achieve low-risk, high-performance 1.6 Tbps systems today—and future-proof your infrastructure for tomorrow.
