p2

High-Speed I/O Evolving to 224G+ Thermal management is becoming a system-level challenge Liquid Cooling Is becoming the Data Center Trend

p3

Reliable sealing and mechanical integration are critical for long-term liquid-cooled system operation Robust Liquid Integration Increasing module power and port density are pushing conventional air cooling to its limits System Thermal Budget Liquid cooling must be integrated into increasingly constrained front-panel space without compromising port density and system accessibility Compact Integration Balanced heat removal across multiple high- power ports is essential for stable system operation Thermal Uniformity Electrical, thermal and mechanical domains must be optimized together rather than independently System Level Co Design Capability to Replicate and Deliver OSFP 224G+ Liquid-Cooling Solutions Within 3 Months Fast Ramping Up Requirements and Challenges of 224G+ I/O Liquid Cooling

p4

High-Speed I/O Is Facing a Growing Thermal Challenge • Higher optical module power • Higher port density • Limited airflow • More complex thermal interaction Thermal performance is becoming a critical part of high-speed I/O design. Data Rate ↑ SERDES Speed ↑ Module Power ↑ Thermal Density ↑↑ Thermal Solution
