The speedy development of AI workloads is driving demand for elevated bandwidth and interconnect density in AI clusters. Optical interconnect energy is a significant factor limiting cluster scalability. Broadcom’s new Sian3 and Sian2M DSPs, together with its complete portfolio of 200G/lane lasers, present unprecedented ranges of energy effectivity and price optimization for next-generation AI infrastructure.
Sian3, a state-of-the-art 3nm 200G/lane PAM4 DSP PHY, delivers the {industry}’s lowest energy consumption for 800G and 1.6T optical transceivers using SMF. Sian3 builds upon the success of Broadcom’s Sian2 DSP, enabling over 20% energy discount for each EML and SiP primarily based 1.6T modules.
Sian2M affords a specialised, optimized answer for 800G and 1.6T short-reach MMF hyperlinks inside AI clusters. By integrating VCSEL drivers and leveraging Broadcom’s market-proven 200G VCSEL expertise, Sian2M unlocks new ranges of efficiency and effectivity for short-reach connectivity. This expertise builds on Broadcom’s established monitor report in optical interconnects, having efficiently deployed over 50 million channels of 100G VCSELs in AI networks.
Broadcom’s Sian3 and Sian2M DSP PHYs, developed together with its portfolio of 200G/lane EML and CWL lasers and its market-proven VCSELs, empower module builders to quickly deal with the rising demand for 200G optics in AI. Broadcom’s 200G EML and PD are already delivery in quantity, delivering the standard, reliability, and efficiency required for AI optical interconnects.
