Broadcom has launched the Sian3 and Sian2M DSP PHYs to address the connectivity demands of AI and machine learning clusters, expanding its 200G/lane product line. The 3nm Sian3 boasts reduced power consumption for 800G and 1.6T optical transceivers over single-mode fiber, while the Sian2M, designed for multimode fiber links, integrates VCSEL drivers. These advancements, according to Broadcom, are critical for supporting scalable AI workloads, reflecting ongoing investment in AI technology and enhancing performance without compromising efficiency or increasing costs.
Broadcom's Sian family of DSP PHYs is foundational to the low-power, high-bandwidth optical connectivity needed for AI/ML clusters.
Our new 3nm Sian3 delivers over 20% power reduction for 1.6T optical modules, while Sian2M with integrated VCSEL drivers and 200G VCSELs brings cost and power efficiency to short reach links.
