NeoPhotonics has announced availability of its extended case temperature QSFP-DD 400G ZR modules with an operating temperature range of up to 80oC. The 400G ZR modules utilise NeoPhotonics’ coherent optical components including its Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tuneable laser. Each of these components can be operated over a wide module case temperature range up to 80oC, enabling the modules to be deployed in extended temperature datacenter environments while reducing cooling requirements and fan power.

“The ability of 400G ZR vendors to offer thermally-optimised designs capable of supporting higher case temperatures will significantly help reduce system cooling requirements,” said Dr. Hacene Chaouch, distinguished engineer at Arista Networks. “This is an important consideration for implementing power efficient data centre interconnect architectures.”

“We are pleased to support customers with high performance 400G ZR modules that operate across a wide thermal envelope, without sacrificing optical performance.” said Tim Jenks, chairman and CEO of NeoPhotonics. “By utilising our leading high speed coherent components technology and optimising the entire optics suite through in-house design, we are able to favourably benefit data centres need to reduce power consumption and improve environmental sustainability,” concluded Jenks.
