Optical Time Domain Reflectometer (OTDR) equipment is essential for testing fiber-optic networks. OTDRs produce measurement files—commonly with extensions like .sor (Script or Standard OTDR Report) or similar vendor variants—that contain trace data, event tables, loss measurements, and metadata. Those binary/ proprietary files are great for analysis within the manufacturer’s software, but they’re not convenient when you need to share results with colleagues, managers, or clients who don’t have the same tools. Converting OTDR .sor files to PDF creates a portable, readable report that preserves plots, summary tables, and key metrics while being widely accessible and easy to archive.

Below is a practical, structured guide to why you’d convert .sor to PDF, the options available, and step‑by‑step examples for typical workflows.
