About OTDR Trace Analysis & Bellcore/Telcordia .SOR Files

An Optical Time-Domain Reflectometer (OTDR) injects high-speed laser pulses into an optical fiber and measures Rayleigh backscattered light and Fresnel reflections returned over distance. The resulting measurement data is stored in the standardized Bellcore/Telcordia GR-196 / SR-4731 (.sor) binary format.

Key Features of the iN2 OTDR Trace Analyzer

  • Binary SOR Record Parser: Decodes General Parameters, Supplier Parameters, Fixed Parameters, Key Events, and Data Points blocks directly in client and server environments.
  • Attenuation Event Detection: Identifies fusion splices, mechanical connectors, optical splitters, macrobends, and fiber end reflection breaks.
  • Topology Mapping: Generates Mermaid topology diagrams representing fiber spans, splice points, and patch panels.
  • Interactive Trace Graph: Canvas-rendered power loss curve (dB) vs. distance (kilometers/feet).

Relevant Standards

OTDR trace parsing follows Telcordia GR-196-CORE (Generic Requirements for Optical Time Domain Reflectometer Type Equipment) and SR-4731 (Standard Optical Record Data Format).
