Sor Files

: A list of all detected points of interest (connectors, splices, etc.).

An is a specialized data format primarily used in fiber optic telecommunications to store measurements from an Optical Time Domain Reflectometer (OTDR). These files follow the Telcordia SR-4731 standard (often referred to as Bellcore format), which ensures that fiber test data can be exchanged and analyzed across different hardware vendors and software platforms. What is an .SOR File? sor files

When you open an .SOR file in analysis software like Fiberizer or FastReporter, it reveals the life story of that specific fiber strand: Data Point What it Represents Importance The raw power level vs. distance. Shows the overall loss (attenuation) of the fiber. Event Table A list of splices and connectors. Pinpoints exactly where a cable was cut or poorly joined. OTDR Setup Pulse width, wavelength, and range. What is an

In the early days of fiber optics, every equipment manufacturer—be it , Viavi (formerly JDSU) , or Anritsu —had its own proprietary format for saving test results.
