WebMar 6, 2024 · Basics operating principle of the Φ-OTDR system The Φ-OTDR system works by sending highly coherent light pulses into a single-mode fiber and the Rayleigh backscattered light detected by a photo-detector (PD) constitutes the signal to be processed. A schematic of the Φ-OTDR system is depicted in figure 1a. A narrow WebThe SOR ("Standard OTDR Record") data format is used to store OTDR (optical time-domain reflectometer ) fiber data. The format is defined by the Telcordia SR-4731, issue 2 standard. While it is a standard, it is unfortunately not open, in that the specifics of the data format are not openly available.
