Abstract

This paper presents an algorithm for detecting and locating connection splice events (faults) in fibre optic cables by the digital signal processing of noisy optical time-domain reflectometry (OTDR) data. Gabor series expansions, Rissanen´s (1978) minimum description length (MDL) criterion, and matched subspace detection methods are employed in the algorithm. It is assumed that the noise is zero-mean, white, Gaussian, and of known variance
