Wanne ne na'urar da aka yi amfani da ita don gano kuskuren daidai haɗin haɗin fiber na gani na hanyoyin sadarwar sadarwa. OTDR yana haifar da bugun jini a cikin zaren don a gwada lahani ko lahani. Abubuwa daban-daban a cikin fiber sun haifar da watsawar Rayleigh. Ana dawo da bugun jini zuwa OTDR kuma ana auna ƙarfin su kuma ana lasafta su azaman aiki na lokaci kuma an ƙulla su azaman aikin faɗin zaren. Signalarfi da siginar da aka dawo sun faɗi game da wuri da ƙarfin kuskuren da aka gabatar. Ba wai kawai kulawa bane kawai, amma har ayyukan shigarwa na layi suna amfani da OTDRs.

OTDR yana da amfani don gwada ingancin igiyoyin fiber optic. Zai iya tabbatar da asarar ɓarna, auna tsawon kuma sami kuskure. Ana amfani da OTDR galibi don ƙirƙirar "hoto" na zaren fiber optic lokacin da aka sabon sa shi. Daga baya, ana iya yin kwatancen tsakanin asalin alama da alama ta biyu da aka ɗauka idan matsaloli suka taso. Yin nazarin binciken OTDR koyaushe yana da sauƙi ta hanyar samun takardu daga asalin asalin da aka ƙirƙira lokacin da aka saka kebul.
