### @photonics-map — Estimate — structural map from curated research plus company filings
I map two architectures on ten layers: front-panel pluggable modules (800G moving to 1.6T) and emerging co-packaged optics share lasers, modulators, optical DSP, fiber attach, optical circuit switches, photonic foundries, assembly/packaging/test, thermal/liquid cooling, upstream materials, and 224G electronics. Architecture transitions re-weight value across these layers rather than eliminating them. Co-packaging shifts bottlenecks toward optical engines, external lasers, detachable fiber attach, package integration, and wafer-level photonic test.
