xMEMS Labs, Inc., the pioneer of monolithic MEMS-based solutions, today announced the expansion of its revolutionary µCooling fan-on-a-chip platform into AI data centers, bringing the industry's first in-module active thermal management solution to high-performance optical transceivers. Originally developed for compact mobile devices, xMEMS µCooling now provides targeted, hyper-localized active cooling for dense, thermally-challenged environments inside 400G, 800G, and 1.6T optical transceivers—a critical yet underserved category in next-gen AI infrastructure.
Unlike conventional cooling approaches that target high-power (kilowatt) processors and GPUs, µCooling focuses on smaller, thermally stressed components that large-scale cooling systems can't reach, such as optical transceiver DSPs, that operate at 18 W TDP or higher. These components introduce thermal challenges and increasingly limit transceiver performance and reliability as data rates scale.
xMEMS' monolithic MEMS fan, fabricated in standard silicon processes, pumps a continuous stream of silent, vibration-free high velocity air pulses and is the only active cooling solution small and thin enough to be embedded inside the transceiver module. Thermal modeling shows that µCooling can remove up to 5 W of localized heat, reducing DSP operating temperatures by over 15% and thermal resistance by more than 20%, enabling higher sustained throughput, improved signal integrity, and extended module lifetimes.
A key innovation in µCooling's system design is its implementation in a dedicated, isolated airflow channel that is thermally coupled to the transceiver's internal heat sources but physically separated from the optical path and core electronics. This architecture ensures that optical components remain protected from dust or contamination, preserving signal clarity and transceiver reliability while still delivering impactful cooling performance.
Market analysts forecast strong growth in high-speed optical connectivity, with Dell'Oro Group projecting 800G and 1.6T transceiver shipments to grow at over 35% CAGR through 2028. As these modules scale in performance and power, cooling challenges are becoming a critical barrier to adoption.
µCooling's solid-state, piezoMEMS design means no motors, no moving bearings, and no mechanical wear, enabling maintenance-free reliability and high-volume manufacturability. Its compact footprint, as small as 9.3 x 7.6 x 1.13 mm, and scalable architecture make it ideal for modular deployments across a wide range of interconnects, including QSFP-DD, OSFP, and future pluggable and co-packaged optics.
With µCooling now serving both mobile and data center markets, xMEMS is delivering on its vision of scalable, solid-state thermal innovation to unlock the next wave of high-performance electronics.
