CPO Cooling: Thermal Kit for Co-Packaged Optics
PHONONIC’S CO-PACKAGED OPTICS:

Unmatched Bandwidth, Efficiency and Reliability

CPO is the Next Frontier to Meet AI Data Center Demands

​Exponentially growing bandwidth demands are driving an inevitable evolution to tightly integrating optics with switching silicon through co-packaged optics to allow networks to keep pace.

By ensuring precise temperature stability for lasers and optical components placed alongside the switch ASIC, solid state TECs enhance performance and stability while enabling higher-density, lower-power and scalable networks.

In addition to addressing the extreme thermal challenges of external laser sources, Phononic’s approach to CPO cooling is perfectly suited for the inevitable market transition to co‑packaged optics more broadly, unlocking additional performance headroom, reducing signal‑path distance and associated energy draw, enabling the scale and bandwidth density required for next‑generation fabrics while not compromising on quality or uptime requirements.

Benefits of Phononic Solutions for CPO

Phononic’s CPO-Ready Thermal Kit: Advanced packaging and localized cooling for co-packaged optical engines in scale out and scale up applications 

Higher Bandwidth Density

Eliminating the need for long, high-speed electrical traces between the switch ASIC and the optical modules, CPO allows for many more optical channels to be placed in the same physical footprint, thus enabling far denser, higher-throughput connects. Phononic’s proprietary 3D modeling enables our FAEs to design solutions that accurately model and mitigate the effects of this increased heat density.

Lower Power

By eliminating the electrical reach between switch ASICs and optical modules, CPO offer significantly lower power requirements as a fundamental design benefit. Further, the energy efficiency of Phononic’s thermoelectric solutions, ~30% lower than competitors, makes Phononic uniquely advantaged in this space.

Improve Uptime & Signal Integrity

Integrating optics directly beside the switch ASIC reduces electrical loss, enables more lanes, higher data rates and denser switch architecture that can scale well. Phononic’s highest quality production and breadth of reliability testing makes us uniquely enabled to deliver these solutions reliably for long-term utilization
