# Fiber-path record

Record the physical path, connector positions, polarity, losses and measured continuity between endpoints.

Revision 2026-11-01. Planning inputs only; unresolved conditions are not approval.

## Path and construction

Include every patch, trunk, cassette and adapter. Connector keying, gender and polish are independent attributes.

- **Project / path ID / route / date:**

- **A and Z port and connector identity:**

- **Media: SMF or MMF type / installed length:**

- **Assembly segments: patch, trunk, breakout, cassette:**

- **Connector type, polish, pinning / gender and key orientation:**

- **Jacket / environment / applicable installation requirement:**

## Position map and continuity

Record the viewing convention used for every connector. A polarity label cannot replace the end-to-end position map.

- **A position → Z position mapping / drawing reference:**

- **Transmit → receive mapping for each active optical lane:**

- **Continuity method / test equipment / calibration date:**

- **Inspection and cleaning record for all mating interfaces:**

- **Measured loss, wavelength and reference method by strand:**

- **Unused fibers / reserved positions / breakout leg lengths:**

## Acceptance evidence

Compare measured values to the documented loss budget and required mapping; do not substitute nominal distance for loss measurements.

- **Applicable budget and source revision:**

- **Failed / unresolved positions and next checks:**

- **As-built drawing, test report and record owner:**
