Broadcom (AVGO) announced on Wednesday morning the availability of its new 3nm 400G/lane optical PAM-4 DCP, the Taurus BCM83640, which was designed to enable optical transceiver manufacturers to cost-effectively deliver low-power 1.6T pluggable modules to meet the growing bandwidth needs for AI data centers.
It supports optical modules from 1.6T to 3.2T.
“Taurus, the industry’s first 1.6T DSP based on 400G/lane I/O, doubles the throughput per lane to enable the next generation of 3.2T optical modules,” said Vijay Janapaty, vice president and general manager of Broadcom’s Physical Layer Products Division. “Crucially, Taurus pushes the IMDD technology envelope into 400G/lane, further reducing power and advancing our roadmap of cost-optimized solutions for connectivity in AI and cloud networks.”
The company expects more than 100M units of 1.6T and 3.2T optical transceivers will be shipped over the next five years, with about half of them using 400G optics.
“High-speed optical interconnects are essential for operation of AI clusters,” said Vladimir Kozlov, CEO and founder of LightCounting. “Doubling of the lane rates has been a proven strategy to keep up with the bandwidth growth, and it is great to see the first 400G per lane solutions becoming available.”
Broadcom has made the Taurus BCM83640 available to its early access customers and partners.
