# Copper DAC Reach Details And API Semantics

Date: 2026-05-09
Actor: Codex
Scope: Copper/DAC/Twinax rows, ATGBICS parser, comparable-product API
Mode: DB-only correction plus tiny API/scraper deploy

## Why

Many remaining highspeed "missing wavelength" and detail gaps were not optical transceiver gaps. They were Copper/DAC/Twinax cable rows. These products do not have optical wavelengths and should be represented with `wavelengths=N/A`, concrete cable length, and cable category.

## DB Correction

Precheck:

- Copper rows missing reach label: `464`
- Copper rows missing reach meters: `467`
- Copper rows missing details: `498`

Found deterministic length evidence in part number or product URL for `342` rows.

Updated those rows:

- `reach_label`
- `reach_meters`
- `wavelengths=N/A`
- cable category
- `details_verified=true` when a product source URL existed

Corrected `78` ATGBICS OSFP cable rows parsed as `SFP`.

Postcheck:

- Copper rows missing reach label: `122`
- Copper rows missing reach meters: `125`
- Copper rows missing details: `158`

## Code Changes

`packages/scraper/src/scrapers/atgbics.ts`:

- detect `OSFP` before `SFP`
- parse decimal meter/kilometer reach such as `0.5m`, `1.5m`, `2.5m`, `30m`, `2km`
- keep Copper/DAC/Twinax/Base-T/RJ45 `wavelengths=N/A`

`packages/api/src/routes/transceivers.ts`:

- allow Copper/DAC/CU comparable products to match each other with `wavelengths=N/A`
- keep numeric wavelength requirement for optical comparable products

## Deployment

- synced scraper to active `/opt/tip`
- `pnpm -C packages/scraper build` passed
- synced API route to active `/opt/tip`
- `pnpm -C packages/api build` passed
- restarted `tip-api`

## Result

Global counters:

- `details_verified`: `11085` -> `11425`
- `fully_verified`: `9861` -> `10170`

Selected vendors:

- ATGBICS: details `7656/8269`, fully `7646/8269`
- NADDOD: details `726/748`, fully `726/748`
- QSFPTEK: details `165/201`, fully `140/201`
- FS.COM: details `373/383`, fully `300/383`
- Flexoptix: details `626/744`, fully `622/744`
- GAO Tek: details `127/414`, fully `2/414`

## Health

Public TIP health after restart:

- status: `healthy`
- load status: `ok`
- memory used: `13%`

## Training Note

TIPLLM should treat Copper/DAC/Twinax products as cable products. They need length, endpoints/form factor, speed, price/image/source evidence, and `wavelengths=N/A`; they must not be forced into optical wavelength rules.
