| description | Research results into the automating the processing of measurement data obtained
from the Brillouin optical reflectometer, light guides containing various types of
optical fibers are presented in this paper. By analyzing the parameters of the
Mandelstam — Brillouin scatter obtained from Brillouin reflectograms, we can
classify optical fibers in the studied telecommunication optical cables. This makes it
possible to evaluate the change of the Brillouin frequency shift and determine the
longitudinal fiber tension. The initial values of the Brillouin frequency shift and the
profile of the Mandelstam — Brillouin scatter spectrum are different for each fiber
type. The programs for automated processing of Brillouin reflectogram data are
discussed. Estimation of the level of the back-reflected signal allows you to identify
the factor, that had a predominant effect on the parameters of the Mandelstam —
Brillouin scatter signal in the studied sections of optical fibers, and to compensate for
the influence of temperature changes in the longitudinal strain distribution graphs.
After that, we can plot a graph of the distribution of longitudinal strain along
the fiber, caused precisely by mechanical influences on optical fibers. Conclusions
about the accuracy of the estimates obtained by various algorithms, based on the
accumulated experience in working with the presented programs are drawn. |
