    • BCM875xx -- Estoque family with 50-Gb/s per lane client side and 50-Gb/s per lane for optical line side interfaces

Broadcom will demonstrate multiple products based on 112Gb PAM-4 PHY with 100Gb PAM-4 EML and 100Gb PAM-4 VCSEL technologies running on Broadcom’s Tomahawk switch platform at the 2021 Optical Fiber Communication Conference and Exhibition (OFC) from June 7th to 11th. Additionally, Broadcom is showcasing its latest 100Gb, 200Gb, 400Gb and 800Gb electro-optics platform solutions in the Broadcom OFC Virtual Exhibit.

“Broadcom offers a complete line of PAM-4 PHYs with direct drive capability that reduce power and cost while enhancing the ease of deployment,” said Vijay Janapaty, vice president and general manager of the Physical Layer Products Division at Broadcom. “Broadcom’s portfolio of optimized solutions for a wide range of optical and line card applications at both 50G/lane and 100G/lane enable customers to rapidly deploy leadership networking solutions to meet the demanding growth of hyperscale cloud datacenters.”

“Broadcom's ability to bring 100G VCSELs and uncooled 100G EMLs to market will enable our customers to address two of the most important challenges facing hyperscale operators - power consumption and bandwidth density,” said Alexis Bjorlin, senior vice president and general manager of the Optical Systems Division at Broadcom. “We are expanding our fab capacities and are continuing to innovate with increased investments in next generation technologies to meet the growing requirements for energy efficient optical interconnects.”

“Growth in demand for optical connectivity in hyperscale datacenters exceeded all expectations. It increased by 80x over the last decade: from 10G in 2010 to 800G by the end of 2020,” commented Dr. Vladimir Kozlov, CEO and founder of LightCounting Market Research. “Broadcom is one of the key suppliers enabling this incredible ramp in speed and complexity of optical interconnects. Their new products, including first 100G VCSELs, 200G EMLs and 112G Direct-Drive PAM-4 PHYs, confirm the company’s commitment to innovation in optical and electronic components supporting the industry.”


The Portofino PHYs are sampling now, and the Centenario and Estoque PHYs are production released. Additionally, Broadcom has begun sampling its 100G MMF and 100G SMF kits to qualified customers. Please contact your local Broadcom sales representative for samples and pricing.
