Typical Configuration

Typically, a fiber Bragg grating Sensing Network is
divided into branches of several sensors connected in
series. On Fig. 4.1 there is a scheme of a usual fiber
Bragg grating sensing branch.
Fig. 4.1
A branch can accommodate sensors with wavelengths
corresponding to all standard HBM FS wavelengths. The
number of sensors in a channel can vary if there is previ­
ous knowledge about the spectral range the sensors will
cover. The major concern is the overlap of adjacent sen­
sors. The available optical channels have simultaneous
acquisition, meaning that the sensing network can have a
large number of fiber Bragg grating sensors interrogated
at the same time.
The employed technology allows multi-functionality
meaning that on the same branch it is possible to mea­
