In some examples of monitoring pipeline integrity using fiber optics, a first set of values that represent an attenuation of a light signal transmitted through an optical fiber positioned adjacent a pipeline to carry fluids and a second set of values that represent a dispersion of the light signal transmitted through the optical fiber are received. 5-10 parts by weight of an organic peroxide. The first protective layer pattern is formed on a first pair of opposite sides of the variable resistance layer pattern. The method further includes performing a beamforming process including instructing transmission of a plurality of signaling beams from one or more transmitters toward the target area. The additive is selected from the group consisting of emulsifiers, defoamers, tackifiers, pigments, humectants, fillers, curing agents, thickeners, wetting agents, biocides, adhesion promoters, colorants, waxes, UV stabilizers, and antioxidants.
