Teb: OTDR yog tsim los ntawm cov qauv ntawm lub teeb backscattering thiab Fresnel reflection. Nws siv lub teeb backscattered generated thaum lub teeb propagates hauv optical fibers kom tau txais cov ntaub ntawv attenuation. Nws tuaj yeem siv los ntsuas fiber ntau attenuation, sib koom ua ke poob, nrhiav cov ntsiab lus fiber ntau tsis ua haujlwm, thiab nkag siab txog kev faib cov fiber ntau raws qhov ntev. Nws yog ib qho cuab yeej tseem ceeb hauv kev tsim kho cable, kev saib xyuas, thiab kev saib xyuas. Nws lub ntsiab qhov taw qhia tsis muaj xws li dynamic ntau yam, rhiab heev, kev daws teeb meem, ntsuas lub sij hawm, thiab qhov muag tsis pom kev.
