Broadcom announced the Taurus BCM83640, a 3nm 400G/lane optical PAM-4 digital signal processor (DSP) designed for AI data centers. This hardware enables the production of low-power 1.6T pluggable optical modules.

The technology doubles the bandwidth per lane compared to previous iterations. It allows for up to 102.4T of switching capacity in a single rack unit and establishes the framework for future 3.2T modules.

Broadcom expects to ship more than 100 million 1.6T and 3.2T optical transceivers over the next five years. These components will support the ongoing build-out of global AI clusters.
