Standard optical cables for building structures monitoring with BOTDR in harsh environments

Popis výsledku v původním jazyce

A fiber optic distributed system based on Brillouin scattering (BOTDR) is an interesting alternative for the load monitoring of building structures and line structures. For the purpose of monitoring deformations, special fiber optic cables with a close bond between optical fibers and cable protective elements are specified. It turns out that standard telecommunication optical cables can be used for some applications in the civil engineering. This paper provides an analysis of the impact of using these cables in harsh environments that is an integral part of engineering structures. The primary interest of this paper is the study of the influence of excessive humidity and temperature variation on the life and optical properties of standard cables implemented in building structures for measurement applications. The results are derived from long-Term testing of standard fiber optic cables implemented in concrete structures in harsh environments to determine the suitability of using these cables for the reliability of long-Term monitoring of building structures such as buildings, bridges or tunnels.
