$LITE $GLW $AAOI $AXTI $COHR Confused by Broadcom's CEO comments on Copper vs. Optics? Let me clear it up. Hock Tan's emphasis on Direct Attach Copper (DAC) as "the way to go" for scale-up isn't a contradiction to the increasing demands for optics products (lasers, transceivers, fiber. They are complementary in east-to-west traffic bottleneck. Copper has its place for short distances but for longer reaches and massive fabrics, Optics are essential. For scale-up (GPU-to-GPU, inside a rack or small cluster), copper wins. Lowest latency, lowest power, lowest cost. No argument there. For scale-out (rack-to-rack, pod-to-pod, massive AI fabrics), optics are essential. Hock said it himself: "In scaling out, we're past that. We use optical. That's fine." See? It's complementary. It's a co-existing ecosystem. Hyperscalers are now connecting 100K to 1M+ GPUs across distributed pods for training and inference at scale. Copper can't handle the distance, heat, power draw, or bandwidth density. Pluggable optics like 800G/1.6T transceivers, lasers, and fiber are the only solution, and demand is, in Hock's own words, "just going nuts." Copper holds its lane. But the next wave of growth lives in scale-out, and that belongs to optics. Don't trade the present. Position for the future.
