Qorvo has introduced five new low-power pulse amplitude modulation-4 (PAM4) optical solutions.
The new products, built on high-performance GaAs, InP and SiGe technologies, connect equipment inside datacentres to efficiently process and deliver ever-increasing volumes of data. The family of transimpedance amplifiers (TIAs) and drivers gives customers a broad range of PAM4 options to support the needs of 100G to 400G optical networks.
“While the current ramp of 100G Ethernet in large datacentres is dramatic, there is considerable interest in implementing the new Ethernet speeds, especially with PAM4 modulation,” remarked Vladimir Kozlov, founder and CEO of LightCounting Market Research. “Qorvo’s new linear drivers and TIAs will support all the new speeds from 25G, 50G, 200G and even 400G.”
Gorden Cook, general manager of the Qorvo Transport Business Unit said, “We are excited to launch the industry’s broadest PAM4 product line, including both drivers and TIAs. These products are designed to more efficiently connect equipment in datacentres and client-side telecom applications. Our complete range of solutions will enable our optical customers to improve performance, reduce total cost and accelerate the implementation of 100G to 400G systems.”
The Qorvo PAM4 family includes three 28GBaud linear drivers and two linear TIAs. The units area said to feature the industry’s leading power efficiency within the range of 200 milliwatts per channel, high gain and high linearity, in a small footprint.
Qorvo’s new linear drivers are now being built into optical network systems. The single-channel TIAs will be available for sampling in April. Additional quad-channel drivers and new TIAs will be available in late 2017.
