Keysight Expands Digital?Layer Error Performance Validation for High?Speed 1.6T Interconnects in AI Data Centers
MWN-AI** Summary
Keysight Technologies, Inc. has unveiled its Functional Interconnect Test Solutions (FITS) portfolio, introducing the first product, FITS-8CH, aimed at validating digital-layer error performance in high-speed interconnects utilized within AI data centers. This innovative solution addresses the increasing complexities and speeds of network components by offering bit error ratio (BER) and forward error correction (FEC) performance validation across the development and manufacturing lifecycle of optical and copper interconnects.
With interconnect speeds climbing to 1.6 Terabits and beyond, ensuring the reliability of these connections is critical for manufacturers. Traditional physical-layer testing approaches validate only isolated electrical lanes, which is insufficient for the rigorous demands of today's networks. FITS-8CH advances this methodology by delivering system-level validation that scrutinizes fully integrated interconnects, revealing error behaviors in protocols such as PAM4 operating at speeds from 53 Gb/s up to 212.5 Gb/s.
Key features of FITS-8CH include simultaneous bi-directional testing across eight channels, a flexible channel architecture designed for various electrical fixtures, and high-quality signal generation compliant with the latest specifications, ensuring accurate measurements. Moreover, automated lane tuning improves measurement consistency, while early detection capabilities identify potential manufacturing and configuration issues, reducing the cost of defective product impacts.
The introduction of FITS-8CH represents a strategic move by Keysight to ensure that manufacturers can confidently release their products into mass production with verified, reliable performance. This solution sets the stage for better component reliability in AI data centers and beyond, drawing from Keysight's extensive measurement expertise to meet the evolving needs of the tech industry.

Real?world error performance validation across the full interconnect lifecycle to reduce risk, lower-costs, and ensure reliable components, sub?assemblies, and complete cable assemblies
Keysight Technologies, Inc. (NYSE: KEYS) today introduced the Functional Interconnect Test Solutions (FITS) portfolio and FITS-8CH, the suite’s first product. FITS-8CH delivers digital-layer bit error ratio (BER) and forward error correction (FEC) performance validation for high-speed optical and copper interconnects used in network equipment and production network infrastructures.

FITS-8CH delivers real world digital-layer interconnect error performance validation across the development and manufacturing lifecycle.
As interconnect speeds increase and designs grow more complex, manufacturers of chips, optical and copper interconnects, and network equipment face mounting pressure to ensure reliability before products reach mass production and throughout the manufacturing process. Traditional physical-layer test tools play a vital role in validating electrical lanes against industry specifications, establishing a strong compliance baseline. Building on this foundation, system-level validation helps extend insight into the performance of fully integrated interconnects and operational sub-assemblies, including error behavior in realistic environments.
Accurate assessment of real?world system conditions is only possible when all interconnect electrical or optical lanes undergo high-speed error-performance validation. Without this testing, the risk of production delays or costly failures in the field increases. This includes validating error performance for high?speed PAM4 electrical lanes operating at 53 Gb/s, 106 Gb/s, and 212 Gb/s, which underpin today’s 400GE, 800GE, and 1.6T Ethernet network architectures.
FITS-8CH addresses this system-level error performance gap by providing multiple-lane error performance validation at the digital layer, supporting PAM4 error performance assessment across all relevant electrical lane speeds and extending beyond physical-layer measurements. This enables reliable validation throughout the design, development, and manufacturing of high-speed interconnects for high-volume deployment in large-scale networks. The chassis also integrates with Keysight’s physical layer test solutions, expanding the number of applications and topologies it supports.
Built for reliability, scale, and manufacturing readiness, FITS?8CH supports today’s network-testing demands, where even marginal error performance can impact large-scale deployments. Key benefits include:
- Multiple-lane BER and FEC Validation : Enables simultaneous, bi?directional real-time testing on all eight transmit and eight receive channels, supporting PAM4 signaling speeds from 53 Gb/s to 212.5 Gb/s. Validating system?level error performance using BER and FEC enables testing of complete optical and copper interconnect assemblies rather than isolated measurements at critical stages, including R&D, product development, in?process manufacturing, end?of?line testing, and system?level qualification. Using this approach, manufacturers can confidently release verified pre?production designs to mass production and benchmark reliability under real?world operating conditions.
- Flexible Channel Architecture: Two complementary channel groups — high?drive outputs and chip?to?module (C2M) interfaces — support a broader range of electrical fixtures and interconnect topologies. This architecture gives teams greater flexibility to support more configurations of electrical fixtures, Ethernet interconnects, active cables, and silicon topologies without redesigning test setups or compromising signal fidelity.
- High?Quality Signal Generation : IEEE P802.3dj?compliant signal generation and excellent signal integrity performance even under difficult conditions provide clean, well?controlled transmit signals required for accurate BER and FEC measurements at all supported channel speeds. By delivering signals that meet defined requirements, teams can evaluate error performance based on the true behavior of the device or interconnect under test, rather than limitations introduced by the test environment. This is especially important in high?speed, multiple-lane designs, where small signal variations can lead to borderline or misleading results.
- Automated Lane Tuning : Optimizes PAM4 signal output performance with lane?by?lane tuning that automatically adjusts transmit tap settings and opens the electrical eye of the PAM4 signal for each lane. This improves measurement consistency and repeatability, reducing the risk of passing assemblies with marginal or borderline error performance.
- Early Detection of Manufacturing and Configuration Issues : Identifies problems such as mechanical misalignment, thermal failures, and non-optimized or incorrect digital signal processor (DSP) tap settings during in?process or end?of?line testing—reducing the costly impact and likelihood of defective products reaching customers.
Kenji Liao, High?Speed Interconnect PM Director, UDE Corporation, said: “With FITS?8CH, Keysight provides the digital?layer error performance analysis we need to verify 1.6T AEC BER?per?lane requirements under realistic operating conditions. The ability to characterize lane?level error behavior across complete interconnect assemblies helps us identify margin issues earlier and maintain consistency as we transition designs into volume production. Integrating this solution into our development and manufacturing workflow strengthens our confidence that UDE’s high?speed interconnects will meet the stringent performance targets our customers expect. The partnership between UDE and Keysight allows us to use this new solution to support error performance validation across development and manufacturing.”
Ram Periakaruppan, Vice President and General Manager, Network Test & Security Solutions, Keysight, said: “As validation requirements move up the stack from the physical layer, our customers increasingly need solutions that scale across development, manufacturing, and deployment. FITS?8CH represents Keysight’s expansion into digital?layer interconnect validation, combining years of deep measurement expertise with the global reach, field support, and portfolio continuity customers rely on for production environments including AI data centers. This is the first offering in our FITS portfolio, a new series of solutions designed to support error performance validation across the entire product lifecycle.”
Keysight will showcase FITS and other network validation solutions in South Hall, booth #1300 from March 17-19, 2026, at the OFC Conference at the Los Angeles Convention Center, Los Angeles, Calif.
