Broadcom Sian Household of DSPs Allow Finest-in-Class 800G and 1.6T Optical Transceivers
Broadcom Inc. (NASDAQ: AVGO) at this time introduced the final availability of SianTM2, 200 Gbps per lane (200G/lane) PAM-4 DSP PHY. Sian2 options 200G/lane electrical and optical interfaces to reinforce the Sian DSP that helps 100 Gbps electrical and 200Gbps optical interfaces. Sian and Sian2 DSPs allow pluggable modules with 200G/lane interfaces which can be foundational to attach subsequent technology AI clusters.
AI cluster sizes and cluster efficiency wants are rising dramatically to assist exploding AI mannequin sizes. Excessive efficiency, low latency, and resilient connectivity are very important for the scale-up and scale-out of subsequent technology AI clusters. For these networks, clients demand dependable optical community connectivity with increased bandwidth, decrease energy, decrease latency and decrease value. This necessitates the migration from the 400G/800G hyperlinks with 100G/lane optics being utilized in AI clusters at this time to 800G/1.6T hyperlinks with 200G/lane optics that Sian2 allows. Broadcom’s Sian2 and Sian DSPs are optimized for 800G and 1.6T optical module platforms and ship unmatched efficiency by doubling the bandwidth with decrease energy, decrease latency and decrease value per bit to facilitate AI information heart scale.
“200G/lane DSP is foundational to high-speed optical hyperlinks for subsequent technology scale-up and scale-out networks within the AI infrastructure,” stated Vijay Janapaty, vp and common supervisor of the Bodily Layer Merchandise Division at Broadcom. “The Sian household of merchandise reinforces Broadcom’s management in optical DSP PHYs and allows our AI information heart clients to deploy high-performance 800G and 1.6T hyperlinks.”
Additional, the mix of Sian2 and Sian PHY and Broadcom’s modern 200G/lane optics, together with electro-absorption modulated laser (EML) and steady wave laser (CWL), offers the best-in-class efficiency and energy consumption enabling information heart operators to cost-effectively scale AI workloads.
“AI market leaders will begin ramping optical modules utilizing 200G/lane in 2025,” commented Dr. Vlad Kozlov, CEO and Chief Analyst at LightCounting. “There’s a race for dominance in AI fueling a requirement for supply in extra of 1M items of 1.6T optical transceivers inside the first 12 months. We’ve by no means seen new merchandise ramping at such fee.”
Sian2 Product Highlights:
- Low energy 5nm 200G/lane DSP resolution enabling sub-28W 1.6T transceivers
- Helps 800G and 1.6T pluggable modules
- Assist for each 212.5-Gb/s and 226.875-Gb/s information charges for InfiniBand and Ethernet purposes
- Assist for a number of FEC choices together with Bypass, Segmented and Concatenated FEC
- Constructed-in low-swing and high-swing laser driver for each SiP and EML based mostly optical modules
- Sub-80ns roundtrip (Ingress + Egress) latency for AI/ML purposes
- Crossbar assist for ease of transceiver design
“Sian2 allows the design of high-speed optical transceivers for subsequent technology switches, community interface playing cards and accelerators with 200G SerDes interfaces,” stated Richard Huang, CEO, Eoptolink Expertise. “The Broadcom Sian2 DSP and Eoptolink’s progressive transceiver design method ends in efficiency main 1.6T pluggable optical transceivers. Mixed with Eoptolink’s excessive quantity manufacturing functionality, this ensures the provision for the rising bandwidth in AI networks.”
“InnoLight is main the trade’s transition to 1.6T with the bottom energy transceiver options, leveraging Broadcom’s Sian2 DSP,” stated Hai Ding, VP of Advertising and marketing, InnoLight Expertise. “As engineering pioneers, we’re redefining optical networking with our cutting-edge improvements, and serving to speed up the deployments of 200G/lane pluggables for subsequent technology AI workloads.”
