Abstract
This work presents results of absolute error estimation performed for non-reflective optical time domain reflectometer (OTDR) event localization during wavelet analysis of optical fiber link trace by continuous Haar wavelet transform. We considered fusion splices of standard singlemode optical fibers with different insertion loss values. Here OTDR indications varied over range 0.020…0.550 dB, while Haar wavelet scaling coefficients were selected from 150 up to 3000. Following comparison of measured and evaluated results allowed for proposition the basic criterion for non-reflective OTDR event localization by wavelet analysis. It is “the center” of this event, and it is characterized by strongly reduced absolute error. During the next step of research, we compared diagrams of event localization error distribution and detected generalized Haar wavelet scaling coefficients that provide mentioned absolute error no more 2 m, which are also presented in this work.
