10:00 a.m. 400G: Looking Forward to 800G and Terabit Speeds
Speaker: Michael Koenigsmann, Application Specialist, Network and Data Center Solutions, Keysight Technologies
400G implementation has begun. New projects to develop the electrical links and optical components to enable 800G optical and electrical transmission are underway. Verifying compliance for 400G and 800G requires careful attention to test setup and execution, and even more discipline moving forward to 800G as design margins continue to decrease. 400G coherent is now a viable alternative to direct detection for data center interconnects (DCI), and development to reach terabit speeds at 100 Gbaud rates for metro/DCI and long-distance networks has started. In this session, you will learn more about practical techniques to minimize validation compliance challenges in 400G direct detection and coherent links, as well as those upcoming in 800G and terabit.
10:45 a.m. Key Considerations in Probing High-Speed Digital Signals
Speaker: Jae Yong Chang, Senior Product Manager, Communications Solutions Group, Keysight Technologies
Modern high-speed digital applications have pushed the limit of high bandwidth and high performance probing solutions. As the bandwidth of your system increases, the edge speed of the signal gets faster, while the size of the chipsets and components tends to be getting smaller, causing PCB layout to become more complex. These trends pose challenges for probing solutions, and there are more things to consider when choosing and using a high-performance probe than a lower-bandwidth, general purpose probe. The higher the performance, the more care is needed. Even though a probe may have an impressive performance specification on the datasheet, the published specified performance may be under very ideal probing conditions. In a real-world high-speed probing situation, which would include using probing accessories to be attached to the probe tips, the probe’s performance may be much worse than the published specified performance. This presentation describes key attributes to consider when probing high-speed digital signals and how Keysight addresses those probing challenges.
