The present discloses a sensor system of optic fibers constituted by an optic fiber including a plurality of sensible elements. Each sensible element has a characteristic spectral band which, in non-disturbed normal conditions, falls into a first wavelengths range, and under the influence of the specific conditions to be detected, it goes into a second wavelengths range without overlapping with the first. The methods for sensing and/or detecting the transmission and/or reflection in the fiber operate within the second wavelengths range to monitor changes in the transparency and/or reflectivity of the fiber provoked by the characteristic spectral travel within the second wavelengths range. The system is characterized for including the means for the distributed realization of the equipment and/or for the structures construction as well as for the detection of the specific conditions delivering alarm signals when the specified conditions appear.
