Highspeed Wavelength DB Backfill
Date: 2026-05-09
Actor: Codex
Scope: TIP highspeed transceivers missing wavelengths
Mode: DB-only, evidence constrained, Erik-safe
Why
After tightening comparable-product logic, missing wavelength evidence became one of the biggest remaining blockers for reliable 1:1 competitor matching. A browser crawl was not needed for rows where the existing DB already contained deterministic optical evidence in part numbers, standard names, notes, or product URLs.
Rule
Only fill wavelengths when the DB text gives deterministic evidence:
- explicit
850nm,1310nm,1311nm, or1550nm - MMF plus SR/SR4/SR8/SRBD/VR/ESR/CSR family =>
850 - SMF plus DR/FR/LR/ER/PSM family =>
1310 - SMF plus CWDM4 =>
1271,1291,1311,1331
Ambiguous rows were skipped.

Training Note
TIPLLM should separate deterministic evidence backfill from source verification. It is safe to infer wavelengths from established optical family codes only when the fiber class matches; otherwise the row must remain unresolved until a vendor-specific parser or source crawl supplies stronger evidence.
