Description

Various analysis methods were applied to OTDR data in an attempt to establish an automated fiber analysis algorithm. The algorithm was to be implemented with a personal computer and an OTDR for automated test purposes. The results of each analysis method were compared for applicability and repeatability. The tests performed on each algorithm involved many combinations of the OTDR’s pulse width, resolution, wavelength, and fiber lengths. After an analysis of the test results, a set of algorithms were chosen whose accuracy and repeatability were affected the least by changes in pulse width, resolution, and wavelength.
