Fully optimized, in every way possible.

Our TECs for optical communication components are superior from end to end—in power consumption, performance vs. size, reliability, and quality. We custom-design our TECs to be optimized for any application and any need.

Engineering benefits.

Icon Image Uncompromised performance

Our TECs deliver 60% higher heat pumping density with 30% lower power consumption, when compared to our competitors’ TECs.


We strive to offer precision at scale when it comes to the assembly process. Our TECs are built in a US-based automated manufacturing facility to scale quickly from design into production, reducing NPI timelines.

Unparalleled design

Our design, simulation, and development proposal allows us to create a device that is tailor-made to exact customer needs, minimizing costly redesign risk and ensuring best-in-class performance.




Our smallest TECs are perfect for TO Can-based laser and detectors from 10G to 25G to 50G and beyond, including PON, 5G mobile and FTTx. Typically less than 3 mm per side and optimized for up to 600 mW of heat.
