Thermoelectric Coolers (TECs) are designed to manage heat and effectively cool transceivers. Phononic’s TECs deliver significantly better power consumption and heat pumping density than alternatives, for a more reliable, higher-performance solution. Our blog offers information about how engineers can use high-quality TECs to increase efficiency and innovate in this competitive space.

Cooled Optics in NG-PON2 Deployment

standard ubiquitous fibers

Posted on Posted on

Next-Generation Passive Optical Network 2 (NG-PON2) is a network standard capable of delivering throughput of up to 40Gbit/s across the network. On a NG-PON2 network, each module is capable of providing up to 10Gbit/s per subscriber, in symmetric upstream and downstream speeds. This network technology broadcasts data across fiber-optic cables for fiber-to-the-x (FTTx) telecommunications. The… Read More

Addressing Reliability in a Non-Hermetic Laser Package


Posted on Posted on

Data transmission rates and performance demands are both increasing, and cooled non-hermetic laser packages are one way of cutting costs while meeting the performance requirements of those demands. But it’s not enough to invest in a non-hermetic solution that can meet demand for just a short lifespan. Optical component manufacturers need to build laser packages… Read More

How a Non-Hermetic Laser Package Saves On Cost

Posted on Posted on

It is increasingly critical for optical transceiver manufacturers to reduce their cost per bit without sacrificing performance. Optical components such as lasers require protection from humidity, condensation, corrosion and other environmental factors, which can all negatively affect performance and the overall life of the package. Addressing these environmental challenges is possible with hermetic packaging that… Read More

Transform Your Industry with Sustainable Solid-State Cooling and Heating

Posted on Posted on

At Phononic, we are reimagining cooling and heating in a way never considered possible – with a solid-state chip. At first, our technology faced skepticism: how could a thumbnail-sized chip ever cool or heat something reliably? However, semiconductor chip-based technology has already led to sustainable solid-state solutions, such as the transistor, solar cell and LED… Read More

How Increasing Data Rates Are Driving a Need to Cool QSFPs

Posted on Posted on

The majority of QSFP (quad small form-factor pluggable) transceivers have traditionally been used uncooled, as they were commonly used in datacenter applications with shorter reach runs where cooling wasn’t really necessary. But data rates are climbing, with 100G becoming more common, and 400G links are starting to be implemented inside the datacenter. These data rate… Read More
