Brillouin based DTS/DSSFrequencyDomainTimeDomainThe activating signal isa propagating pulse andthe position is given bythe time of flight. The frequency shift iscomputed by recording theBrillouin spectrum at differentfrequencies and extractingthe maximum peak location.Spatial resolution is givenby the pulse width.BOTDR: spontaneous scattering, single end access Omnisens 2020BOTDA: stimulated scattering, loop configurationIPLOCA’s Fall Novel Construction Session – Geneva – 21/10/20207

Rayleigh based DASIntensity/phaseDomainTimeDomainThe activating signal isa propagating pulse andthe position is given bythe time of flight.Spatial resolution is givenby the pulse width. The intensity/phase variations ofthe Rayleigh signal as a functionof time provides acousticsignature. Omnisens 20208IPLOCA’s Fall Novel Construction Session – Geneva – 21/10/2020

How does it work? Leak Detection DTS based – Standard telecomsFOC with loose tube. DAS based – Standard telecomsFOC with either loose tube or tightbuffer. Optical fibers must be SingleMode (ITU-T G652C/D or G655) HDPE deployment possible butdirect ground burial recommended12 Omnisens 2020IPLOCA’s Fall Novel Construction Session – Geneva – 21/10/2020
