Tark Thermal Solutions’ Micro TECs Empower Next-Gen Pluggables for AI Data Centers

Tark Thermal Solutions (formerly Laird Thermal Systems) has expanded its OptoTEC™ MBX thermoelectric cooler (TEC) family to include new custom options engineered to address emerging thermal challenges in ultra-high-speed optical transceivers fueling the next wave of AI-driven data centers.

As hyperscale data centers and AI clusters deploy increasingly larger models and interconnect more servers, the bandwidth required between compute and storage nodes is pushing transmission speeds from 800Gbps, to 1.6Tbps per link. These higher-speed links produce more heat in smaller spaces and are requiring increasingly compact, efficient, and reliable thermal management to stabilize sensitive laser temperatures, mitigate crosstalk, and preserve signal integrity over long-haul and multi-wavelength links. Effective miniaturized thermal management is critical to preventing signal degradation, maintaining laser wavelength stability and ensuring reliability.

Engineered for Speed, Miniaturization and Efficiency

The OptoTEC MBX Series of micro thermoelectric coolers maintain tight temperature control while fitting within the space constraints of cutting-edge optical pluggables.

• Precision Cooling: new thermoelectric materials and high-precision manufacturing deliver rapid thermal response for ultra-compact optical pluggables, including 800G, 1.6T, and anticipated 3.2T modules
• Micro Footprint: OptoTEC MBX TECs feature footprints as small as 1.5mm x 1.1mm and thicknesses down to 0.65mm, integrating seamlessly into advanced transceiver designs with minimal space and weight penalty
• Optimized for Performance: OptoTEC MBX achieves heat pumping densities up to 43 W/cm² at a lower operating current than traditional thermoelectric coolers, reducing total power draw for dense data center deployments

“Our MBX Series redefines thermal management for a new era of optical pluggables. Engineered for thin profiles, high heat packing densities and scalability, MBX coolers position AI data centers and telecom providers to meet tomorrow’s bandwidth demands with confidence,” said Andrew Dereka, Thermoelectrics Product Director, Tark Thermal Solutions.

As hyperscale applications push optical links to new performance heights, the MBX Series ensures that innovation in transceiver speed is matched by innovation in miniaturized, cost-effective, and highly reliable thermal control.
