Breaking the 51.2T Thermal Wall: The ADTEK Infinity 0G Cassette

As next-generation AI computing clusters and All-Optical Data Centers (AODC) scale toward 51.2T, 800G, and 1.6T, CPO/NPO switches face four critical bottlenecks:

1. Overcrowded PCB footprintsthat limit component placement.
2. Mid-plane partitionsobstructing global airflow and cooling.
3. Excessive on-site fiber splicingand rework liabilities.
4. Restricted port expansionwithin rigid chassis structures.

To resolve these physical conflicts in 51.2T and 102.4T platforms, ADTEK unveiled the Infinity 0G Cassette at OFC. This side-mounted switching module is custom-engineered to integrate zero PCB footprint, unobstructed airflow, and factory pre-termination into a single solution.

1. Physical Architecture: 15mm Ultra-Slim Side-Wall Layout

The 15mm ultra-slim integrated structure is the core differentiator of the Infinity 0G.

• Zero PCB Footprint:By migrating optical switching and fiber management to the chassis side-walls, critical board resources—like ASICs and power modules—are fully reclaimed.
• 3D Layout Efficiency:We transform 2D front-panel congestion into a high-efficiency 3D layout, optimizing internal structure and Electromagnetic Compatibility (EMC).
• Lateral Airflow Protection:The 15mm profile is strictly maintained to ensure it never encroaches on cooling channels for the core ASIC.

1. Thermal Management: 100% Airflow Retention

• Eliminating Thermal Barriers:By removing the front-end partitioning mid-plane, the ASIC cooling path is fully opened.
• Sustained High-Load Computing:System cooling efficiency remains at 100% of its theoretical design value even under maximum port configurations, satisfying the strict thermal thresholds of 6T+ components.

III. Factory-Level Control: Pre-Terminated “Plug-and-Play”

The Infinity 0G Cassette is manufactured via factory-controlled processes and shipped in sealed protective packaging.

• Zero Field Work:No on-site grinding, polishing, or manual fiber cutting is required.
• Standardized Quality:Every unit is pre-tested to avoid link failures caused by manual errors, drastically compressing construction cycles and O&M costs.

1. Dual Deployment Configurations

The system enables elastic expansion from 128 to 144 ports without modifying the chassis structure.

Conclusion: As AI clusters scale from 51.2T toward 102.4T, the Infinity 0G Cassette redefines CPO/NPO optical topology—not as a hardware increment, but as a thermal-interconnect co-design. It provides a compliant, stable, and cost-effective foundation for next-generation, low-carbon computing infrastructure.
