About SOR files
The .SOR file is a Standard OTDR Record file used in the telecommunications industry to store optical fiber test data. An Optical Time-Domain Reflectometer (OTDR) generates these files to document fiber length, splice losses, and fault locations. These files follow the Telcordia SR-4731 standard and are typically opened using specialized hardware and software from vendors like EXFO or Viavi Solutions. The main disadvantage of the .SOR format is its specialized binary structure. You cannot open it natively on Windows, macOS, or standard mobile devices. Sharing these files with clients or civil engineers is frustrating because they rarely have expensive, licensed telecom software installed to view the trace graphs. To make the data usable, you need to convert it. For client reporting and archiving the visual trace graph, convert .SOR to PDF. To extract the raw data points and event tables for spreadsheet analysis, convert to CSV. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your SOR file, detects the exact format, and lets you read the text inside.

The SOR Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SOR converter.
