Low latency linear pluggable optics with PCIe 6.0® demonstrated
Alphawave Semi has announced its collaboration with InnoLight Technology, the leader in data center optics, to bring a low power, low latency linear pluggable optics (LPO) demonstration to OFC 2024.
Operating at 64 Gbps per lane, this demonstration showcases Alphawave Semi’s PCIe 6.0® subsystem (Controller + PHY) with InnoLight’s LPO OSFP optics, breaking down barriers to disaggregated networking and enabling connectivity at the datacenter scale. By delivering a complete PCIe 6.0 subsystem featuring Alphawave Semi’s controller IP matched with its industry-leading proven PAM4 SerDes PHY and by collaborating with InnoLight as an industry-leading optics supplier, Alphawave Semi is fostering an ecosystem for accelerating the deployment of optical connectivity and memory coherency solutions, which are essential for scaling AI workloads in next-generation data center infrastructure.
Osa Mok, Chief Marketing Officer at InnoLight, said, “The collaboration between Alphawave Semi and InnoLight demonstrates PCIe 6.0 optical connectivity that offers both low power consumption and low latency, tailored to meet the demanding requirements of high-bandwidth and high-density AI networks. Alphawave Semi’s PAM4 DSP physical layer technology, leveraged with InnoLight’s LPO OSFP, empowers hyperscalers to implement next-generation disaggregated, composable networks.“
Tony Chan Carusone, CTO at Alphawave Semi, said, “Our collaboration with InnoLight aims to be a significant driver for accelerating the adoption of PCIe technology over optics. The combination of InnoLight’s market-leading optical offering with Alphawave Semi’s robust DSP technology showcases how PCIe technology over optics can enable our customers to massively scale connectivity for their compute and data processing AI workloads.”
The Alphawave Semi PCIe Controller + PHY subsystem is an extremely power-efficient, low-latency, and highly reliable interface IP, having been built off the industry’s most successful PAM4 SerDes IP. It is available on the most advanced technology nodes. In AI and high-performance computing (HPC) systems where memory performance is key, the Alphawave Semi PCIe 6.0 Subsystem can be expanded to support CXL 3.0 with a PCIe and CXL Controller and enable memory coherency at the data center level.
InnoLight offers a wide range of low power, low latency 400G, 800G, and 1.6T LPO offerings for AI workloads at data center scale, with a silicon photonics platform, with expected capabilities to support PCIe Gen 6 and beyond optical connectivity. InnoLight is also a founding member of LPO-MSA, and is actively working with the industry ecosystem to promote wide adoption of LPO for AI networking and computing applications.
