Tark Thermal Solutions’ MBX Series Micro Thermoelectric Coolers Empower Next-Gen Pluggables for AI Data Centers
Tark Thermal Solutions, the leading global manufacturer of thermal management solutions (formerly Laird Thermal Systems), introduces new custom options in the Series of OptoTEC™ MBX thermoelectric coolers (TECs), 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 reliable thermal management to stabilize sensitive laser temperatures, mitigate crosstalk, and thermal management is critical to preventing signal degradation, maintaining laser wavelength stability and ensuring reliability.
The OptoTEC MBX Series of micro thermoelectric coolers maintain tight temperature control
: 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
: 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
: 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
position AI data centers and telecom providers to meet tomorrow’s bandwidth demands with
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-

The MBX Series provides active temperature stabilization for laser diodes and other heat- sensitive components within ultra-compact optical pluggables. By tightly controlling the laser junction temperature, MBX TECs help maintain wavelength stability and minimize signal
MBX modules utilize advanced thermoelectric materials and high-precision assembly processes that enable heat pumping densities up to 43 W/cm². Footprints start as small as 1.5 mm × 1.1 mm with thicknesses down to 0.65 mm, making integration possible in penalties.
In addition to their reduced form factor, MBX TECs are optimized for lower operating current at a given heat load. This lowers overall power consumption in dense data center environments. Their fast thermal response also allows precise control loops for modulated or rapidly varying heat loads typical of high-speed optics.
They are designed for pluggable optical transceiver formats such as 800G and 1.6T OSFP/ QSFP-DD modules, as well as emerging 3.2T coherent links. Any application with tight thermal requirements, high channel counts, and limited PCB real estate, such as AI cluster
