Modeling of Correlation Optical Reflectometer with a Probing Signal in the Form of Pseudo-Random Sequences Fragments

Abstract

Traditionally, the most informative means of measuring the parameters of linear optical paths of fiberoptic communication systems is an optical time domain reflectometer with a simple probing signal. The disadvantages of such a reflectometer are known limitations on the dynamic range and resolution. To improve the listed characteristics, the paper considers the possibility of using the technology of correlation reflectometers with a probing signal in the form of fragments of pseudo-random sequences. The study carried out in this work proves the advantages of such reflectometers over traditional ones.
