EXFO OTDR Viewer 6.18

EXFO OTDR Viewer is a desktop application designed to open, visualize, and interpret optical time-domain reflectometer (OTDR) trace files produced by EXFO test instruments. It helps fiber-optic technicians and network operators assess link integrity, validate splices and connectors, and document test results without needing the original instrument.

Key capabilities:

• View OTDR traces with zoom, pan, and movable markers/cursors
• Event table with automatic identification of splices, connectors, and faults
• Measurements for distance, insertion loss, reflectance, and overall link quality
• Comparison of traces across wavelengths or test runs (when supported by the trace)
• Annotations, pass/fail thresholds, and basic report generation/export
• Support for standard .sor (Telcordia/Bellcore) trace files for easy sharing

Note: Features may vary by version and by the capabilities embedded in the trace files.
