Broadcom announced the launch of the industry’s first 400G-per-lane optical digital signal processor (DSP), designed to support next-generation AI data center networks. The new 3-nanometer Taurus BCM83640 DSP enables 1.6-terabit optical transceivers with improved bandwidth density, efficiency and lower power consumption.
The technology doubles the bandwidth per optical lane compared with current 200G architectures and supports future 3.2-terabit modules, paving the way for network switches capable of up to 204.8T capacity. The solution is aimed at meeting the rapidly increasing connectivity demands of AI clusters and large-scale cloud infrastructure.
Broadcom said the Taurus BCM83640 has begun sampling with early access customers and partners, with the technology expected to play a key role in the next generation of high-speed optical interconnects for AI and cloud data centers.
