NeoPhotonics Corporation, a developer of silicon photonics and advanced hybrid photonic integrated circuit-based lasers, modules and subsystems for bandwidth-intensive, high speed communications networks, has announced the availability of its extended case temperature QSFP-DD 400 gigabit (G) ZR modules.
These 400 G ZR modules utilize the company’s coherent optical components including its silicon photonics

Each of these components can be operated over a wide module case temperature range up to 80° C, enabling the 400 G ZR modules to be deployed in extended temperature datacenter environments while reducing cooling requirements and fan power.
“We are pleased to support customers with high performance 400 G ZR modules that operate across a wide thermal envelope, without sacrificing optical performance,” said Tim Jenks, chairman and CEO of NeoPhotonics. “By utilizing our leading high speed coherent components technology and optimizing the entire optics suite through in-house design, we are able to favorably benefit data centers need to reduce power consumption and improve environmental sustainability.”
