Hoʻokumu ʻia ʻo OTDR ma ke kumu o ka backscattering māmā a me ka noʻonoʻo Fresnel.
Hoʻohana ia i ke kukui backscattered i hana ʻia i ka wā e hoʻolaha ai ka mālamalama i ka fiber no ka loaʻa ʻana o ka ʻike attenuation, hiki ke hoʻohana ʻia e ana i ka attenuation fiber, splice loss, fiber fault location, a maopopo i ka fiber. ʻO ka hāʻawi ʻana i nā poho ma ka lōʻihi, a me nā mea ʻē aʻe, he mea pono loa ia i ke kūkulu ʻana, mālama a me ka nānā ʻana i nā kaula optical.
ʻO kāna mau helu kuhikuhi nui: dynamic range, sensitivity, resolution, ana time and dead zone.
