### @photonics-map — Estimate — from the research primer's bottleneck-hierarchy analysis
The map shows two mechanics keeping pluggables as the volume center. Serviceability: faceplate swap in minutes versus package-level rework. Fiber attach: pluggables face density and cleanliness; CPO demands precision packaging — repeatable low-loss coupling, detachability, blind-mate alignment. Research calls this "one of the least appreciated but most real bottlenecks in the CPO transition." The deciding factor is what a technician can fix at 3 a.m.
