Thermoelectric Cooling for Pump Lasers

Product Overview

Pump lasers have extremely high performance demands – after all, you don’t want to have performance issues when you’re dealing with transatlantic cable runs. Butterfly packages require reliable, larger-sized, higher-density heat pumping TECs to support the amplification and transfer of data across extremely long distances.

Phononic’s high-performance, low power-consumption TECs withstand the challenges inherent in pump laser applications. When the standard of global communications is at stake and there’s a massive construction budget on the line, you can’t settle for standard products. All of our solutions are custom-designed to meet your needs.
