Fiber optic cables for measuring strain

Fiber optic strain sensing cables are connected to interrogators (electronic measurement and evaluation devices). These operate on the basis of the Brillouin principle, for example, and require single-mode fibers.

Types of sensing cable: fiber optic cables for measuring strain

A measurement plan designed to suit the intended use is necessary for measurement of the various physical parameters. 

For fiber optic strain sensing cables, the fiber optic cable must be held in such a way that the action of the expansion forces on the fibers is as linear and as direct as possible.

Key factors in the choice of cable are environmental parameters such as the location of the cable assembly or embedding, temperature range, mechanical load, water and dust, chemical substances, ionising radiation and hydrostatic pressure.

Typical applications are structural monitoring, and detection of earth movements and avalanches.
