Ts'ebetso ea ho lekanya ea DAS: laser e ntša likhahla tse bobebe haufi le fiber, 'me leseli le itseng le kena-kenana le leseli la ketsahalo ka mokhoa oa ho khutlela morao ho pulse. Ka mor'a hore lebone la tšitiso le khutlele morao, lebone la tšitiso ea morao-rao le khutlela mochineng oa ho sebetsana le matšoao, 'me lets'oao la acoustic la vibration le haufi le fiber le tlisoa sesebelisoa sa ho sebetsana le matšoao. Kaha lebelo la khanya le lula le sa fetohe, tekanyo ea ho sisinyeha ha acoustic ka mithara ea fiber e ka fumanoa.
