NeoPhotonics Corp of San Jose, CA, USA – a vertically integrated designer and manufacturer of silicon photonics and hybrid photonic integrated circuit (PIC)-based lasers, modules and subsystems for high-speed communications – has announced availability of its extended-case-temperature QSFP-DD 400G ZR modules.
The 400G ZR modules utilize NeoPhotonics’ coherent optical components including its silicon photonics coherent optical sub-assembly (COSA) and low-power-consumption, ultra-narrow-linewidth Nano-ITLA (integrated tunable laser assembly). Each of these components can be operated over a wide module case temperature range up to 80°C. This enables the 400G ZR modules to be deployed in extended-temperature data-center environments while reducing cooling requirements and fan power.
“The ability of 400G ZR vendors to offer thermally optimized designs capable of supporting higher case temperatures will significantly help reduce system cooling requirements,” comments Dr Hacene Chaouch, distinguished engineer at Arista Networks. “This is an important consideration for implementing power-efficient data-center interconnect architectures,” he adds.
“We are pleased to support customers with high-performance 400G ZR modules that operate across a wide thermal envelope, without sacrificing optical performance,” says chairman & CEO Tim Jenks. “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.”
