Bluebird 1.6T optical DSP

A 224 Gbps-per-lane PAM4 optical DSP with four or eight lanes, offered as a full DSP and as a linear receive optics version. The company says 1.6T modules built with it stay under 20 watts.

Why it matters to the stock. It is the company's most advanced optical DSP and the one most tied to 1.6T module upgrades in AI clusters.
