NeoPhotonics intros QSFP-DD 400G ZR modules with extended case temperatures

March 15, 2021
NeoPhotonics says its 400G ZR transceiver modules reduce system cooling requirements and save electrical power in data centers.

NeoPhotonics (NYSE: NPTN), a developer of silicon photonics and advanced hybrid photonic integrated circuit-based lasers, modules and subsystems for bandwidth-intensive, high speed communications networks, recently announced availability of its extended case temperature QSFP-DD 400G ZR modules.

The new 400G ZR modules utilize NeoPhotonics’ coherent optical components, including its silicon photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tunable laser.

According to the company, each of these components can be operated over a wide module case temperature range up to 80 deg. C. This enables the NeoPhotonics 400G ZR modules to be deployed in extended temperature data center environments while reducing cooling requirements and fan power.

“We are pleased to support customers with high performance 400G ZR modules that operate across a wide thermal envelope, without sacrificing optical performance,” commented 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."

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