Versatile 1.6 Terabit Ethernet platform in portable bench top or rack mount solutions, with application support for validating silicon chips to network equipment performance

Keysight Technologies Inc.announced the Interconnect Test System, an advanced software solution, and the Interconnect and Network Performance Tester 1600GE hardware traffic emulator it runs on. This cohesive solution validates AI infrastructure, network components, and data center interconnects from 200GE to 1600GE, expanding on the capabilities of the recently announced Interconnect and Network Performance Tester 800GE bench top. The ITS software runs on both the 800GE and 1600GE Interconnect and Network Performance Tester platforms.

For decades, validating network interconnect performance required a manual, time-consuming process with limited or no automation and needed advanced programming skills to write scripts. That process also lacked a centralized system to organize and store interconnect data and reports, making tracking and replicating tests and configurations difficult. With the increasing diversity and scale of AI and data center interconnects, these traditional test methods cannot accurately predict and measure the reliability of today’s complex production networks.

The new Interconnect and Network Performance Tester 1600GE, with ITS software, delivers a holistic system that can organize, store, and use data intelligently to automate interconnect validation in high-speed Ethernet networks and AI data centers. Benefits of the solution include:

• Adaptable and versatile high-speed Ethernet platform – The INPT-1600GE platform is lightweight and office quiet, supporting high power consumption optical receivers up to 40 watts. Available as a portable bench top unit or rack mount chassis, both models support 1x1600GE, 2x800GE, 4x400GE, and 8x200GE to validate a broad range of Ethernet devices and interconnects that use 212Gb/s electrical lane interfaces. The bench top model has a built-in handle for easy movement inside or outside the lab. The INPT-1600GE assesses the reliability, stability, and interoperability of silicon chips, optical transceivers, active cables, and networking equipment at speeds from 200GE to 1600GE PAM4 for layers 1 through 3 on any port.
• Redefines interconnect data storage and organization – The ITS software includes a first-of-its-kind, US patent pending Interconnect Library (IL) that introduces a new way to organize, retrieve, and use interconnect data, including Common Management Interface Specification (CMIS) data. CMIS standardizes how high-speed interconnects are programmed and how the data is retrieved and used in networking systems. This cutting-edge library organizes all data and creates a comprehensive record that can be used to create and execute new tests. Once a record is created, it is automatically added to the IL self-serve database, where users can retrieve, reuse, edit, and update records. This dramatically increases productivity and accelerates the creation of automated test suites without advanced programming.
• Optimize interconnect validation efficiency – The browser-based ITS software includes a robust and fast graphical user interface (GUI) that allows multiple users to simultaneously run or schedule tests using the application’s advanced multi-user test scheduler. Using this tool increases test case throughput, allowing more tests to run unattended by a greater number of users.
• Automated report generator – Allows users to report on all the data from the IL records, including test results and CMIS data that includes PASS/FAIL information. This helps streamline the development process for interconnects and can also be used for manufacturing test applications using automated reports.

Khushrow Machhi, Senior Director of Marketing, Physical Layer Products Division at Broadcom, said: “As the industry moves toward 1.6T networking, ensuring signal integrity and error correction at these unprecedented speeds is critical. Broadcom is excited to collaborate with Keysight in developing cutting-edge testing solutions that address the challenges of higher modulation schemes, SerDes advancements, and forward error correction. Our combined expertise will help accelerate the deployment of 1.6T technology, paving the way for the future of high-speed data centers and AI-driven infrastructure.”

Andy Moorwood, Vice President, Hardware Engineering, Network Test & Security Solutions, Keysight, said: “Keysight’s ITS software is the industry’s first comprehensive solution for validating performance in high-speed Ethernet and AI data center interconnects. It helps reduce device failures and drastically reduces the time needed to characterize various interconnects. Moving from a manual and tedious process to one that enables faster, more accurate test suite automation without complex programming significantly boosts productivity.”

Ram Periakaruppan, Vice President and General Manager, Network Test & Security Solutions, Keysight, said: “Keysight is working with the majority of global standards bodies and manufacturers of silicon chips, optical and copper interconnects using 224Gb/s electrical lane interfaces to accelerate development of the ecosystem for 800GE and 1.6T AI network infrastructures. Our 1.6T and 800GE hardware platforms, combined with the ITS software, enable critical interconnect performance evaluations and tremendous gains in testbed productivity. This equips our customers with the tools they need to deploy highly stable and reliable solutions into their networks.”

Modules range in power levels from 750W up to 2kW, with a top power density of 5kW/in3

New Vicor DCM3717 and DCM3735 DC-DC power modules support the growing trend of 48V-centric power delivery networks that provide greater power system efficiency, power density and lower weight versus 12V based PDNs. The DCM products are non-isolated, regulated DC-DC converters, operating from a 40 – 60V input to generate a regulated output adjustable from 10V to 12.5V. The DCM3717 family is available in two power ranges, 750W and 1kW, and the DCM3735 is a 2kW device. These new DCM products can be paralleled to rapidly scale system power levels.

With industry-leading power density at 5kW/in3, these new DCM products enable power system designers to deploy high-performance 48V power delivery networks for legacy 12V loads and achieve significant size, weight and efficiency benefits. The 5.2mm low-profile surface-mount package is thermally adept, easing thermal management system design.

The DCM3717S60E13G5TN1 (750W) and DCM3717S60D13K0TN1 (1000W) are available (size: 36.7 x 17.3 x 5.2mm), and the DCM3735S60D13L0TN1 (2000W / size: 36.7 x 35.4 x 5.2mm) will be available later this year.

Enabling easy conversion from high voltage to 12V via a 48V hub

Power delivery networks are making a decisive shift from 12V to 48V architectures to take advantage of higher efficiency. The benefits of using 48V have been illustrated in high-performance computing, automotive and in many other applications. However, seizing this opportunity presents many power system design challenges for legacy systems that have been optimized around 12V architectures for decades. Vicor, the leader in 48V DC-DC power conversion, is easing the transition with a 48V-centric power module approach to power systems design and, as with other 48V power modules, this new family of non-isolated DCM products can be used in conjunction with the Vicor BCM high-voltage fixed-ratio bus converter family that converts from high voltage (800V and 400V) to 48V. Once a 48V bus is established, Vicor DCM products can efficiently convert from 48V to a regulated 12V.

Industrial applications are transitioning to 48V PDNs

Growth applications, such as battery formation and test and semiconductor automated test equipment, aspire to rapidly transition to 48V PDNs to gain a competitive advantage but are hindered by existing investments in 12V power conversion. Some BFT implementations, for example, have been optimized to convert 12V to the battery cell load and cannot be readily re-engineered for 48V. The DCM3717/3735 products enable BFT systems engineers to preserve their existing investment by bridging 48V and 12V to create a high-performance 48V PDN.

The Vicor broad ecosystem of 48V centric power modules enables easy scalability and unprecedented flexibility when converting from high voltage to point-of-load for a wide variety of applications.

New analog products from TI accurately measure currents and voltages with the highest resolution, enabling robots to perform detailed and complex tasks

Texas Instruments introduced the industry’s first functionally isolated modulators, helping designers achieve more precise motor control in compact robot designs. The new AMC0106M05, AMC0136 and AMC0106M25 isolated modulators enable increased precision and higher resolution of 12 to 14 effective number of bits for accurate and reliable phase current sensing and DC voltage sensing measurements. Offered in a small leadless package, the new products in TI’s isolated analog-to-digital converter portfolio help designers achieve smooth torque operation and fine motor control, while decreasing size and cost in low-voltage (<60V) robotics designs.

Why it matters

Engineers today are challenged to design smarter robots to perform more detailed tasks. The galvanically isolated modulators enable robotics engineers to achieve precise motor control and system protection in smaller, more sophisticated designs. This precision makes it possible for robots to complete a variety of complex tasks, such as threading a needle or handling small nuts and bolts. In addition, the small size of the new modulators—measuring just 3.5mm x 2.7mm—requires 50% less board space than competing reinforced isolation solutions. With this decrease in size, designers have more space to incorporate additional features that support precise control and reliable operation in compact robot applications.

“These modulators from TI enable designers to increase robotics accuracy and productivity in new use cases and smaller form factors, from the factory floor to the operating room,” said Karthik Vasanth, vice president and general manager of Data Converters and Clocks at TI. “For example, where humanoid robots could previously only complete simple tasks, our new functionally isolated modulators now allow them to carry out more dexterous and precise jobs.”
