Vector indexing algorithm for post processing of OTDR data

The paper details the vector indexing algorithm for post processing of data in optical time domain reflectometer. Post processing is necessary in OTDR for event detection and feature extraction from the acquired traces. The vector indexing algorithm uses the acquired data trace to extract accurate event location and improve upon the spatial resolution of the OTDR. The proposed algorithm has been tested on our self-developed OTDR board and its performance has been benchmarked against the real measured event locations.
