OSP Fiber Optic OTDR Bidirectional Test Report

Outside plant fiber acceptance inspection template for documenting bidirectional OTDR traces, splice-by-splice loss, end-to-end attenuation, and reflectance results for fiber optic links.

Test Identification and Route Details

• Project name, route ID, and fiber span identified
• Test date and time recorded
• Cable type, fiber count, and wavelength(s) documented
• Test endpoints and direction of travel identified
• Reference standard and acceptance criteria noted
  Document project acceptance criteria and applicable standard references, such as TIA-568 requirements and project specifications.

Safety and Test Readiness

• Work area controlled and traffic/public exposure managed
  Verify the test area is safe for OSP field work, including traffic control, access control, and site-specific hazards.
• PPE appropriate for OSP fiber work in use
  Confirm required PPE is worn, including eye protection and any site-specific PPE for the work location.
• Fiber ends cleaned, capped, and laser safety precautions followed
  Confirm connector endfaces are clean and optical safety practices are followed before connecting test equipment.
• OTDR, launch fiber, receive fiber, and adapters available and verified
• Test equipment calibration status valid
  Verify the OTDR and any power meter or light source used are within calibration or verification interval.

Bidirectional OTDR Trace Capture

• Trace captured from end A to end B
  Upload the OTDR trace image or file reference for the A-to-B direction.
• Trace captured from end B to end A
  Upload the OTDR trace image or file reference for the B-to-A direction.
• Launch fiber length sufficient to resolve first event
  Record launch fiber length used for the test. It must be long enough to separate the first connector or splice event from the OTDR dead zone.
• Receive fiber length sufficient to resolve end event
• OTDR pulse width, range, and averaging settings documented
• Event table exported or attached
  Attach the OTDR event table or file export used to support splice and connector analysis.

Splice-by-Splice and Connector Measurements

• Splice loss values recorded for each event
  Document splice-by-splice loss for all identified fusion or mechanical splice events.
• Connector insertion loss recorded for each end connection
• Reflectance measured for connector events
  Record reflectance or return loss values for connector events where applicable.
• Bidirectional average loss calculated for each splice
  Confirm splice loss is averaged from both directions where required by the test method.
• Non-conforming events identified and explained

End-to-End Attenuation and Acceptance

• End-to-end attenuation recorded for each wavelength
  Document total link attenuation for each tested wavelength and direction as applicable.
• Measured attenuation within project acceptance limit
• Reflectance or ORL within project acceptance limit
• Fiber continuity verified end to end

Closeout and Documentation

• All trace files, event tables, and supporting photos attached
• Deficiencies and corrective actions documented
• Inspector signature
• Customer or AHJ witness signature
  Use when required by project specifications, customer handoff, or Authority Having Jurisdiction.
