TEF 2025: Overcoming 400G Technology Challenges
Jim Hsieh, Senior Technical Manager at Mediatek, presents on the critical need for industry-wide collaboration to advance 400G technology, emphasizing cooperation among connector manufacturers, cable vendors, silicon vendors, optical vendors, and system providers. He explains that 400G’s challenging initial conditions require precise link training protocols, standardized error correction methodologies, and robust Ethernet standards to ensure interoperability and reliable connections across all industry participants.
The Ethernet Alliance held its Technology Exploration Forum (TEF) exploring Ethernet for AI in Mountain View, CA on December 2-3, 2025. The @NextGenInfra team was on the ground to capture thought leader perspectives on changes and evolution needed in Ethernet to support AI/ML workloads — both on the front-end and back-end (scale out).
